Emergency situations during hair transplant and how to avoid them.DrAnilKumarGargRejuv
Hair Transplant surgery is a safe outpatient day surgery.
Emergencies are uncommon but can appear suddenly.
Many of the emergencies, but not all, are preventable through attentive pre-operative and intraoperative care.
Clinic doctors and support staff must be prepared to manage emergencies.
Potential medical conditions which may convert into life-threatening emergencies during Hair transplant are-
Medication- Lidocaine toxicity, drug interactions( beta-blockers with adrenaline, lidocaine with Dilantin ), over sedation.
Allergy/ Anaphylactic shock
Hypotension- due to hypovolemia, cardiovascular shock, vasovagal syndrome.
Cardiovascular- Angina, myocardial infarction, arrhythmias (cardiac arrest).
Pulmonary- Dyspnea, Asthma, respiratory arrest.
Neurologic- seizures, stroke
Coagulation- bleeding diathesis
Trauma- accidental injury/fall
MEDICAL EMERGENCIES IN DENTAL CLINIC.pptxBhargabeeDas2
Dentists must be prepared to manage medical emergencies which may arise in practice.
Medical emergencies were most likely to occur during and after local anesthesia, primarily during tooth extraction and endodontics. Over 60% of the emergencies were syncope, with hyperventilation the next most frequent at 7%.
The extent of treatment by the dentist requires preparation, prevention and then management, as necessary. Prevention is accomplished by conducting a thorough medical history with appropriate alterations to dental treatment as required. The most important aspect of nearly all medical emergencies in the dental office is to prevent, or correct, insufficient oxygenation of the brain and heart. Therefore, the management of all medical emergencies should include ensuring that oxygenated blood is being delivered to these critical organs. This is consistent with basic cardiopulmonary resuscitation, with which the dentist must be competent.

Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.
The dimensions of healthcare quality refer to various attributes or aspects that define the standard of healthcare services. These dimensions are used to evaluate, measure, and improve the quality of care provided to patients. A comprehensive understanding of these dimensions ensures that healthcare systems can address various aspects of patient care effectively and holistically. Dimensions of Healthcare Quality and Performance of care include the following; Appropriateness, Availability, Competence, Continuity, Effectiveness, Efficiency, Efficacy, Prevention, Respect and Care, Safety as well as Timeliness.

7. Vasovagal Syncope
Cause:
Loss of vasomotor tone due to a massive
parasympathetic discharge leading to
decreased pulse rate, and decreased
blood pressure which leads to cerebral
hypoxia and pooling of blood.
8. Fainting: Vasovagal Syncope
In Dentistry
• The most common cause is psychogenic due to fear
and anxiety; especially from local anesthetic
• Most common between the ages of 16 and 35
• Males more prone than females
• Fainting is considered SERIOUS in PEDIATRIC patients
and patients OVER 40 years of age
9. Vasovagal Syncope
Signs/Symptoms:
1. Frightened anxious patient.
2. Decreased pulse rate.
3. Decreased blood pressure.
4. Cool, moist, clammy skin.
5. Pale appearance.
Treatment:
1. Place patient in
Trendelenberg’s position.
2. Monitor vital signs.
3. Administer aromatic spirits
of ammonia.
4. Apply cold towel to
forehead.
5. Administer 100% oxygen.

– Psychotropics, Sedatives, and Tranquilizers.
– Age: increases with increasing age
– Prolonged recumbency
12. Postural Hypotension
Signs/Symptoms:
• Decrease in BP and loss of
consciousness without
prodromal signs and
symptoms
• Heart rate is normal, unlike
Bradycardia in Vasovagal
Syncope.
• All manifestations of
unconsciousness
• When patient is placed in
the supine position,
consciousness rapidly
returns.
Treatment:
• Stop treatment
• Assess consciousness
• Place patient in the supine
position with legs elevated
• Oxygen
• Monitor vital signs
• Slowly reposition patient
13. Fainting: Postural Hypotension
Pregnancy (2 forms of hypotension)
1. Postural hypotension: during the first trimester
when getting out of bed in the morning; does not
reoccur during the day.
2. Supine hypotensive syndrome of pregnancy occurs
in the third trimester. If the patient is in the supine
position for more than 3 to 7 minutes, the uterus
can compress the inferior vena cava decreasing
venous return from the legs. Turning the patient on
her left or right side will alleviate the pressure and
blood flow returns to normal.
