Delayed recovery of unconsciousness from anaesthesiaSourav Mondal
This document discusses causes of delayed recovery of consciousness after anesthesia. It identifies several patient factors, drug factors, and pharmacological causes that can result in prolonged unconsciousness. Patient factors include extremes of age, gender differences, genetic polymorphisms, comorbidities, body habitus, and preexisting cognitive conditions. Drug factors include residual drug effects, potentiation by other medications, drug interactions, and the type and duration of anesthetic used. Specific anesthetic agents like opioids, benzodiazepines, intravenous agents, and volatile agents are discussed in terms of their mechanisms of causing respiratory depression and prolonged sedation. Accurate diagnosis and treatment of the underlying cause is important for proper management.
Principles and Practice of Sedation in Intensive Care Unit (ICU)Apollo Hospitals
Distress is common amongst critically ill patients in ICU, especially those who are intubated or have difficulty communicating with their caregivers [1]. Distress in ICU generally presents as agitation. It needs to be treated for patient comfort & if left untreated increases sympathetic tone with untoward physiologic effects [2].
Before a sedative agent is initiated to manage agitation, the cause of distress should be identified & treated. Common causes of distress in critically ill patients include:-anxiety, pain, delirium, dyspnoea and neuromuscular paralysis. These etiologies may occur separately or in combination.
Major Depressive Disorder is characterized by one or more episodes of depression without a history of mania. Its etiology is complex with several factors like genetics, environment, and biology contributing. Symptoms include decreased levels of neurotransmitters like serotonin and norepinephrine. Treatment involves pharmacological therapies like SSRIs, TCAs, and MAOIs to reduce symptoms as well as psychotherapy. The goals are to reduce acute symptoms, facilitate a return to normal functioning, and prevent future episodes. Treatment is conducted over acute, continuation, and maintenance phases.

This document discusses the melatonin receptor agonist ramelteon, which is approved for the treatment of insomnia. It summarizes ramelteon's mechanism of action as a highly selective agonist for melatonin receptors MT1 and MT2, which are involved in regulating sleep-wake cycles. Clinical studies showed that ramelteon significantly reduced time to fall asleep and increased total sleep time compared to placebo, without next-day residual effects. In contrast, benzodiazepines and other sedative-hypnotics can cause dependence, abuse potential, and daytime sedation. Ramelteon has no serious adverse effects and no abuse potential even at high doses, making it preferable to other
This editorial discusses tramadol, a synthetic analgesic drug that is classified as an opioid but has additional mechanisms of action involving serotonin and norepinephrine reuptake inhibition. The editorial summarizes tramadol's pharmacology, drug interactions, evidence for its use, issues with misuse, and implications for use in children. It notes that tramadol has gained disproportionate attention given its short time on the market and discusses ongoing debates around its classification, prescribing patterns, and risks versus benefits especially in certain populations like children.

Medication-induced movement disorder (Extra-Pyramidal Side Effects, EPSE) occurs due to treatment with antipsychotic medications. It can also be defined as physical symptoms, including tremor, slurred speech, akathesia, dystonia, anxiety, distress, paranoia, and bradyphrenia, that are primarily associated with improper dosing of or unusual reactions to neuroleptic (antipsychotic) medications.
Though they are commonly caused by the typical antipsychotics, but can also be caused by the atypical.
The adverse consequences of these syndromes can be minimized by vigilant clinicians who systematically examine patients at risk for these disorders and who manage them properly when discovered.
The best management is, of course, prevention, which starts with the judicious prescription of neuroleptics, and an awareness of the potential for certain nonpsychiatric medications to cause the same movement disorders.
The document discusses guidelines for sedation, analgesia, and neuromuscular blockade in the adult ICU. It describes the benefits of daily sedation interruption and titration programs to lighten sedation levels. It provides an overview of options for sedation and analgesia, including opioids, benzodiazepines, propofol, dexmedetomidine, and neuromuscular blockade. It also addresses risks of oversedation like delirium and discusses strategies for preventing and treating delirium.
This document provides information about different types of anesthesia including general and local anesthesia. It defines anesthesia as the loss of sensation caused by administering drugs. General anesthesia causes unconsciousness and involves multiple agents to achieve analgesia, amnesia, and muscle relaxation during surgery. Local anesthesia only affects a limited area of the body without loss of consciousness. The document discusses various general anesthetic agents like barbiturates, non-barbiturates, gases, and volatile liquids. It also covers local anesthetic agents and types of regional anesthesia like spinal and epidural anesthesia.

This study compared the hemodynamic effects and seizure activity of thiopentone sodium and propofol when used as inducing agents in 100 patients undergoing modified electroconvulsive therapy (MECT). Results showed:
1) Propofol maintained significantly better hemodynamics compared to thiopentone, with lower heart rate, systolic blood pressure, and diastolic blood pressure.
2) Seizure time was significantly lower with propofol compared to thiopentone, but therapeutic effect and complication rates were comparable.
3) Recovery from anesthesia post-MECT was significantly quicker with propofol compared to thiopentone.

An adverse drug reaction (ADR) is an unwanted or harmful reaction that occurs when taking a medication. ADRs can range from mild to severe or life-threatening. They are classified based on their cause and severity. Serious ADRs are those that result in death, are life-threatening, cause hospitalization or disability, or require intervention to prevent impairment or damage. Managing ADRs involves withdrawing the drug if possible and treating the effects. All suspected ADRs should be reported to help monitor drug safety.
The document provides information about various classes of pharmacology drugs:
Hypnotics like benzodiazepines promote sleep by enhancing the effects of the neurotransmitter GABA. Neuroleptics/antipsychotics like phenothiazines are used to treat psychosis by blocking dopamine receptors. General anesthetics induce unconsciousness, amnesia, and analgesia for surgery. They work by depressing the central nervous system. Non-narcotic analgesics like NSAIDs reduce pain and inflammation by inhibiting prostaglandin synthesis while narcotics mimic endogenous opioids to relieve pain. Benzodiazepines are commonly used anxiolytics that enhance GABA effects in the limbic system to reduce anxiety. In
This document summarizes a seminar on anticonvulsant agents. It discusses the pathophysiology and classification of epilepsy, as well as the mechanisms of action and structure-activity relationships of common anticonvulsant drugs like phenytoin, primidone, and ethosuximide. It also reviews the clinical uses of anticonvulsants to treat different seizure types and neurological conditions. The document concludes that identifying and treating associated neurobehavioral disorders can improve quality of life for people with epilepsy.
This document provides an overview of topics relevant to an anesthesiology clerkship rotation, including:
1) A definition of general anesthesia and discussion of associated risks.
2) Guidelines for preoperative assessment and optimization of patient medical conditions such as cardiovascular, respiratory, endocrine, and renal diseases.
3) Descriptions of important hereditary conditions like malignant hyperthermia that require special anesthetic considerations.
The document discusses the history and development of the field of neuroanesthesia, covering topics like common complications during neurosurgery and recommendations for different anesthetic regimens and agents based on patient conditions like Alzheimer's, Parkinson's, or epilepsy. It also examines complications that can occur from regional anesthesia techniques and recommendations to reduce risks from anticoagulation in patients undergoing regional blocks.
The document discusses awareness under anesthesia, including definitions of key terms like consciousness, memory, and awareness. It describes the causes of intraoperative awareness as unexpected variability in drug requirements, light anesthesia levels, masking of inadequate depth, and machine errors. Prevention strategies include premedication, checking equipment, and brain monitoring. Consequences can include psychological trauma, and management involves deepening anesthesia if awareness is suspected.

This presentation provides information on serotonin syndrome, including its recognition, management, and prevention. Serotonin syndrome is a potentially life-threatening complication that can result from interactions between certain drugs that affect serotonin levels, such as antidepressants, pain medications, herbal supplements, and illegal drugs. The presentation reviews diagnostic criteria and recommends aggressive treatment including discontinuing causative agents, using benzodiazepines for symptoms, and intubation and ventilation for severe hyperthermia. With increased awareness, education of patients, and early recognition, serotonin syndrome can be prevented.
This document discusses insomnia and treatments for it, focusing on hypnotic medications. It defines insomnia as difficulty initiating or maintaining sleep. Cognitive behavioral therapy and sleep hygiene measures are recommended for long-term insomnia to address anxiety and behaviors that worsen sleep. Hypnotic medications like benzodiazepines are recommended for short-term use by targeting the GABA system to reduce arousal and promote sleep. While effective, benzodiazepines can cause dependence and withdrawal symptoms with long-term use. The document compares properties of different classes of hypnotic medications and their mechanisms of action and metabolism.

ABSTRACT- BACKGROUND & OBJECTIVES: Control of post spinal shivering is essential for optimal
peri-operative care as shivering is a cause of discomfort and dissatisfaction in patients undergoing operations under spinal
anaesthesia. The aim of the study is to assess the efficacy and safety of intravenous Clonidine, Dexmedetomidine and
Tramadol in the treatment of post spinal intra-operative shivering.
MATERIALS AND METHODS: In this prospective, double blind, randomized study, 90 ASA grade I and II patients of
patients aged 18 – 50 rears, scheduled for various routine surgical procedures under spinal anaesthesia with hyperbaric
Bupivacaine and who developed shivering were selected. The patients were divided into three groups of 30 each.
Group- C (n=30) comprised of the patients who received Clonidine 0.5mcg/kg intravenously, Group-D (n=30) who
received Dexmedetomidine 0.5mcg/kg IV and Group T (n=30) receiving Tramadol 2 mg/kg (maximum 100mg) IV. The
efficacy and response rate of the study drugs were evaluated and recorded. Side effects like, nausea, vomiting,
hypotension, bradycardia, sedation and headache, if present, were recorded. All data were analyzed using Chi-square test
and student-t test and expressed in >0.05, (which is insignificant) and < 0.05, (which is significant differences).
RESULTS: There were significant differences in the total response rate between the drugs (p > 0.05), Tramadol showing
the highest response rate (100%). Time taken from the start of treatment to cessation of shivering was significantly less
(p<0.05) in Dexmedetomidine group, but Tramadol group shows complete control of post spinal shivering with none or
lesser and mild degree of side effects with a single dose.
CONCLUSION: Complete control of post spinal intra-operative shivering with less or no severe side effects could be
achieved with Tramadol in comparisons to clonidine and Dexmedetomidine.

This document summarizes a study that evaluated the knowledge, attitudes, and practices of oncology health professionals in Australia regarding complementary and alternative medicine (CAM). The study surveyed 99 oncology physicians, nurses, and pharmacists. It found that the professionals had moderate knowledge of CAMs but felt unprepared to advise patients due to a lack of expertise. While they acknowledged potential benefits of CAMs, they also expressed safety concerns. Fewer than 40% of patients were open to discussing CAMs with their providers, hindered by a lack of scientific evidence and guidelines. The study reveals a need for more CAM education for oncology clinicians to improve patient-provider discussions and decision-making regarding CAM use.
This document discusses adaptive filtering techniques, specifically the Least Mean Square (LMS) and Recursive Least Squares (RLS) algorithms. It describes the basic structure and operation of adaptive filters, including their use of error signals as feedback to optimize transfer functions. The LMS algorithm is commonly used due to its computational simplicity, while RLS provides faster convergence but with higher complexity. The document proposes a modified Delayed LMS (DLMS) adaptive filter architecture to reduce adaptation delay by feeding error computations forward through pipeline stages. Simulation results show this DLMS design achieves lower area, delay and power compared to conventional LMS and RLS filters.

Pharmacological Treatment of Postoperative Sleep Disorders in the
First Two Nights. Examination in Detail
M. RehanaBhanu1
, S. MasumVali2
, M. ShakirBasha3
Abstract
The restorative benefits of sleep are especially important to take into account in the immediate postoperative period. Acute sleep
disturbances after surgery are seldom discussed in the medical literature. Most pharmaceutical treatments include the use of
benzodiazepines, however because of their potential for adverse effects, it is highly advised that a tailored approach be used. The
purpose of this narrative review was to analyze effective pharmacological treatments for acute sleep problems in the first 48 hours
after surgery in patients who had planned medical operations. A narrative search was performed in the databases of Embase, PubMed,
and Cochrane. No studies other than randomized controlled trials and systematic reviews were examined.
The effectiveness of pharmaceutical therapies for acute sleep problems, the methods of administration, and the effect on postoperative
descents were the major outcomes. The original search turned up 271 papers, however only 7 were suitable for inclusion.
Pharmacological treatments like 5mg of Zolpidem before bed and >900mg of Gabapentin are often used. The first postoperative phase
is crucial for treating these diseases, and it has been found that Dexmedetomidine IV infusion at a dosage of 0.05 mcg/kg/h is
effective.

1. Introduction
Age, surgery, anesthetics, postoperative anxiety, and other
physical and mental stresses [1-3] (Table 1) all increase the
risk of developing a sleep problem in the postoperative period.
In most cases, the symptoms of these diseases only endure for
a few days and go away completely after the underlying cause
of stress has been removed or the individual has learned to
cope with it.

A therapeutic intervention is necessary in certain circumstances [4-6] because sleep disturbances, despite their brief duration, are a
severe worry for both patients and their loved ones and hinder
patients' recovery. It is possible that poor sleep habits formed
in the postoperative period contribute to the development of
chronic sleep disorder in patients who suffer these problems
for more than a few days. Indeed, mental and physical health,
and the optimal physiological and emotional functioning that
results, are inextricably linked to one's sleep habits and sleep
cycle. Regarding memory, mood, metabolic function, and
inflammatory response, some research suggests a link between
sleep disruptions and these illnesses [7].
Reduced total sleep time and slow-wave sleep, reduced REM
(Rapid Eye Movement) sleep, and an increased length of the
second stage of non-REM sleep are all sleep-related
abnormalities that occur in the early postoperative period [8].
It has also been reported that in the first few days after
surgery, patients typically report suffering sleep disruptions
and sleep deprivation [9].
Surgical stress, environmental factors, medical treatments [9-
14], and comorbidities like obesity, hypertension, diabetes,
cardiovascular disease, and postoperative pain, the latter being
a major risk factor for sleep disorders that acts in a
bidirectional way since the pain experienced after surgery can
make it difficult to fall asleep or stay asleep. Therefore, a
cautious approach is required for the proper management of
these disorders in the early postoperative period, as is taking
into account the efficacy of the available treatments and their
potential side effects, as sometimes drugs may be effective,
but they can cause sedation, putting patients at risk for
respiratory distress, aspiration pneumonitis, confusion, falls,
and delirium [7]. The short-term treatment of sleep disorders
with Z-drugs, non-benzodiazepines hypnotic agents
(Zolpidem, Zopiclone, Eszopiclone, Zaleplon), and

benzodiazepines has been reported to be effective in non-
surgical patients [17]. Trazadone, diphenhydramine, and
gabapentinoids have also been used off-label with some
success in the management of sleep disorders.
As a result of the above, this literature review aims to describe
in detail the various pharmacological alternatives available for
the pharmacological therapy of acute sleep disturbances
occurring within 48 hours following surgery in hospitalized
patients. It is important to note that in the current study, acute
sleep disorders are defined as conditions in which
pharmacological management is warranted because patients in
the postoperative period experience difficulties initiating or
maintaining sleep, insufficient sleep duration and quality, and
early morning awakening.

3.1 Zolpidem
Zolpidem, like benzodiazepines, is a GABAA receptor
chloride channel agonist that enhances GABA inhibitory
effects and causes sleepiness. Improvements in sleep quality
were associated with less knee pain in the early postoperative
period for patients taking Zolpidem, according to a study by
Gong (2015) [22] on the effects of sleep quality on early
recovery after total knee arthroplasty (n=148). Sublingual
pills, an oral spray, regular tablets, and extended-release
tablets are all ways to take this medication. Headache,
dizziness, sleepiness, nausea, diarrhea, myalgias, rebound
insomnia, memory and behavior difficulties have all been
linked to the usage of Zolpidem in adults. Zolpidem has been
shown to be equally effective as benzodiazepines in treating
insomnia while causing less negative side effects [28].
Another randomized, double-blind research comparing
Zolpidem to a placebo in 20 patients ( 60 years) undergoing
hip and knee replacements under spinal anesthesia found no
significant difference between groups after surgery. This study
was conducted by Krenk et al. (2014) [29]. Consequently, our
data suggests that giving patients 5mg of Zolpidem on the first
night after surgery to treat their sleep disturbances is
beneficial. The current labeling for Zolpidem recommends a
starting dosage of 5 mg taken before bedtime for the short-
term treatment of insomnia due to difficulty initiating sleep.
3.2 Gabapentin
Gabapentin is an alkylated derivative of the neurotransmitter
gamma-aminobutyric acid (GABA) that is used to treat
partial-onset seizures and postherpetic neuralgia in adults.
Binding to the 2-1 subunit of voltage-gated Ca2+ channels
causes a decrease in the influx of Ca2+ and the release of
excitatory neurotransmitters like glutamate at the synapse,
thereby decreasing the hyperexcitability of the nociceptive
neurons and their ability to transmit pain and cause central
sensitization. When given before to surgery, Gabapentin
lessens the need for opioids and their negative side effects, as
well as the severity of postoperative pain. Sedation and
dizziness are the most common adverse reactions, however
peripheral edema has also been seen [30,31]. In a study of
patients who had undergone a complete knee replacement,
Gabapentin was shown to increase slow-sleep waves, decrease
early waking events, and preserve REM sleep compared to a
placebo group [32,33].
While Lo et al. [34] noted that the risk of sedation and visual
disturbances increased with increasing doses of Gabapentin, it
was reported that the drug improved patients' sleep quality
during the first two nights following surgery.
In contrast to these results, Eloy et al. [19] found that
Gabapentin does not reduce postoperative pain or improve
sleep quality when tested in a study of patients who had
undergone total hip or knee replacement using the Pittsburg
Sleep Quality Index (PSQI). Similarly, Spence et al. [21]
found that Gabapentin did not enhance the length or quality of
sleep in individuals undergoing shoulder arthroscopy
compared to a placebo. Polysomnographic studies have been
conducted to examine the impact of gabapentin on sleep
disturbances. For instance, one research indicated that a
dosage of 600 mg/day was most effective in treating insomnia
in a group of 18 individuals [18], while another reported that a
dose of up to 900 mg/day was necessary (540 mg/day average
dose) [35]. Dosages stated there may differ from those found
in the research since Gabapentin was titrated for up to 3 weeks
to find the optimal dosage.
Since there is not enough information to identify the proper
amount and the kind of surgical operation it may be used for,
the results given above suggest that regular use of Gabapentin
8. Indo-Am.J.Pharm&Bio.Sc.,2020 ISSN: 2347-2251www.iajpb.com
Vol.18,Issue 3,Sep 2020
for the treatment of sleep disturbances during the
postoperative period should not be suggested.
3.3 Pregabalin
Indicated for the management of severe diabetic peripheral
neuropathy, postherpetic neuralgia, partial-onset seizures,
fibromyalgia, and neuropathic pain associated with spinal cord
injury, Pregabalin, like Gabapentin, operates via voltage-
dependent calcium channels [30]. Pregabalin's effectiveness in
treating sleep problems is little understood. Polysomnographic
studies, however, have shown that it affects sleep-
maintenance insomnia and is helpful in the management of
sleep disorders due to a wide variety of conditions, such as
fibromyalgia, GAD, neuropathic pain, and postherpetic
neuralgia [36,37].
Pregabalin was shown to be useful in reducing the frequency
of sleep disruptions on the first postoperative night, according
to a randomized, placebo-controlled, double-blind experiment
conducted by Buvanendran et al. [24]. Patients using
pregabalin experienced significantly (P 0.0001) less disruption
to their sleep than those taking a placebo.
3.4 Melatonin
Pineal glands produce melatonin, an endogenous hormone.
There is evidence that melatonin plays a function in sleep
regulation due to the association between its elevated
nocturnal production and its higher levels at the start of nights
[38,39]. The FDA does not oversee the use of melatonin as a
treatment for sleep problems since it is considered an
alternative medicine.
Melatonin has been indicated for the therapy of acute sleep
disturbances [39], and it has been documented in patients with
sleep abnormalities related to their circadian rhythm and in
geriatric people. The effects of melatonin on postoperative
sleep and pain in patients who had undergone total knee
arthroplasty were studied in a randomized, double-blind pilot
research by Kirksey et al. [40].
When compared to the placebo group, those who were given
melatonin did not sleep any more effectively (p = 0.15) or for
any longer (p=0.067) [36].
A randomized, placebo-controlled, double-blind trial
conducted by Andersen et al. [25] on 44 patients who had
cholecystectomy found that a melatonin dosage of 10mg had
no impact on sleep quality in the first three days after surgery.
Although headache and dizziness are the most often reported
adverse effects of this medication, some users have also seen
an improvement in their ability to fall asleep faster. Patients
who had laparoscopic cholecystectomy and were given
melatonin at 5mg/day did not demonstrate any increase in
sleep quality compared to those who were given placebos, as
stated by Gögenur et al. [41]. These results suggest that
melatonin is not useful for treating sleep disturbances in those
receiving postoperative treatment.
Dexmedetomidine, 3.5mg/kg
Dexmedetomidine is a highly selective agonist of alpha-2
adrenergic receptors with sedative, analgesic, and anxiolytic
effects that does not affect respiratory rate. It binds to alpha-2
receptors with a 1610-fold higher affinity than alpha-1
receptors [42]. The adrenergic inputs that promote awakening
in the cortex, basal forebrain, thalamus, and hypothalamus are
reduced when it binds to -2 adrenergic receptors in the locus
coeruleus, thereby exerting a function in the initiation and
maintenance of sleep. In addition, they produce sleep via
regulating non-adrenergic neurons in the thalamus and the
frontal lobes [43]. Dexmedetomidine induces a condition
similar to N2 sleep by acting on an endogenous sleep-
promoting route, making it unique among sedatives.
Dexmedetomidine aids in maintaining sleep cycles and
improving sleep efficiency in critical care unit patients who
are ventilator-dependent. It has also been shown that infusion
of this medicine enhances total sleep time [44] in elderly
patients under postoperative care who are not on ventilators.
Dexmedetomidine promotes N3 stage sleep in a dose-
dependent manner without affecting the psychomotor
vigilance test scores, according to a prospective, randomized,
and crossover pilot study by Akeju et al. [43] in 10 patients
comparing the effects of dexmedetomidine and zolpidem for
sleep induction.
Researchers Chen et al. [45] studied the effects of
postoperative dexmedetomidine infusion on sleep quality in
60 patients undergoing abdominal hysterectomy. They
discovered that giving patients undergoing abdominal
hysterectomy a combination of dexmedetomidine infusion and
sufentanil resulted in significantly better sleep efficiency and
fewer early waking episodes than giving patients sufentanil
alone. These patients also had improved pain management.
Patients who had partial laryngectomy and were given
Dexmedetomidine and sufentanil slept better in the
postoperative period than those who were given sufentanil
alone, according to a research by Qin et al. [36].
4 - Discourse
The effectiveness of pharmaceutical therapy of acute sleep
disturbances in patients requiring postoperative care is little
documented. The findings of the research by Eloy et al. show
that gabapentin does not help patients with sleep following

orthopedic surgery. Better sleep quality for the first two nights
following surgery was a secondary result in the trial by Lunn
et al., which compared groups treated with gabapentin and
placebo. Both groups (300 mg gabapentin or placebo 1 hour
before surgery) in a 2011 trial on shoulder surgery conducted
by Spence et al. slept similarly [21]. Gong L, et al., discovered
in their research [22] revealedzolpidem-treated patients
showed more improvement in quality of life, and that there
was a discernible link between sleep quality and mobility.
These findings indicated that higher quality sleep aids patients
in their recovery after a total knee or hip replacement. Chen et
al. [9] found that giving patients dexmedetomidine after
surgery considerably enhanced the quality of their sleep.
Patients using pregabalin slept better than those taking a
placebo while hospitalized, according to a research by
Buvanendran et al. [24]. Anderson et al. [25] observed no
statistically significant changes in sleep quality between the
placebo and intravenous melatonin groups. Because of this,
non-pharmacological measures like earplugs and masks [46]
and complementary measures commonly known as sleep
hygiene should be considered as the first options for the
management of these disorders; however, they are time-
consuming, and sometimes the rapid discharge of these
patients does not allow for their implementation. Acute sleep
problems may be induced by the stress experienced by
patients in the days leading up to surgery, thus it is not
uncommon for adult patients without a history of sleep
disorder to report having poor sleep patterns following
surgery. These diseases tend to be short-lived and fade away
after the triggering event has passed. With this in mind, the
objective of pharmacologic treatments in postoperative care is
to lessen the emotional and physiological strain that patients
experience as a result of sleep deprivation. In addition,
treating short-term sleep issues might lessen the likelihood of
long-term sleep problems from stemming from abnormal
cognitive and behavioral reactions to sleep loss. For the
treatment of severe sleep disturbances interfering with these
patients' daily lives and recovery, hypnotic medication therapy
should be explored following the adoption of non-
pharmacological therapies; nevertheless, hypnotics should
only be recommended for brief periods of time.
Benzodiazepines including the Z-drugs zaleplon, zolpidem,
and zopiclone are some of the hypnotics that have been
licensed for the treatment of insomnia.
4. Conclusions
Patients in intensive care units or with postoperative delirium
are good candidates for the management of sleep disorders
through the intravenous administration of Dexmedetomidine.
Gabapentin at doses greater than 900 mg/day and Zolpidem at
a dose of 5 mg at night may have a positive impact on sleep
efficacy in the early postoperative period. However, hypnotics
have undesirable side effects, thus non-pharmacological
approaches are strongly encouraged. Sleep quality in
postoperative care patients has not been well studied to
develop a standard of measurement or to identify the most
effective pharmacological therapy.
