Neuromuscular monitoring, also known as train of four monitoring, is a technique used during recovery from the application of general anesthesia to objectively determine how well a patient's muscles are able to function. It involves the application of electrical stimulation to nerves and recording of muscle response using, for example, an acceleromyograph. Neuromuscular monitoring is typically used when neuromuscular-blocking drugs have been part of the general anesthesia and the doctor wishes to avoid postoperative residual curarization (PORC) in the patient, that is, the residual paralysis of muscles stemming from these drugs.
mapleson circuits used in anesthesia practice, are in their way out but it is as important to know the mechanism with which the gases flow to and fro through them.

Factors affecting the speed of induction and recovery from volatile anesthesia.
Anesthesia complications range from minor to catastrophic.
complications of general anesthesia might be due to difficulty in airway management or ventilation.
Also the complication might be due to cardiac arrhythmias and poor response to anesthetic effect during induction or maintenance or even the emergence from anesthesia.
So, the the systematic response to the effect of the anesthesia may occur at any time during surgery.
Some of the complications:
Hypoxia, arrhythmia, hypotension , hypertension, regurgitation and aspiration, hypothermia hypoglycemia, coronary ischemia, embolism, persistent apnea delayed recovery , and many others.
also regional anesthesia has its complications like nerve injury, post spinal headache.
Toxicity from local anesthesia is one of the important complication might occur during local infiltration.

The importance of preoperative assessment and evaluation to prepare the patient to surgical procedure is directly proportional with the degree of successful of any surgical procedure.
So, good preoperative assessment and evolution is necessary to avoid the morbidity and mortality that expected to the surgical procedures.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

5. • Vaporizers: a specifically calibrated plenum
vaporizers.
The physical properties of boiling point and
saturated vapor pressure are very similar to
Halothane, so the vaporizer design is also closely
related.
7. Cardiovascular:
• Minimal left ventricular depression.
• SVR ↓↓
• B.P ↓↓
• H.R ↑

8. Respiratory:
• As Halothane, except in less tachypnea.
( Net result more ↓ in Vm.)
• Even 0.1 MAC can blunt the normal
ventilatory drive.
• Irritation to upper airway, increases bronchial
secretions and salivary secretions.
2 MAC → irritation at 50% of patients.
• Good bronchodilator but < Halothane.
9. Cerebral:
• CBF ↑
• ICP ↑
• CMRO2 ↓↓
The CBF & ICP increased by > 1 MAC less than
Halothane & can be reversed by
hyperventilation.
• At 2 MAC → silent EEG.

micromole/L is quoted as the threshold for
renal toxicity , Sevoflurane metabolism can
produce levels above this threshold, yet
clinically significant renal dysfunction has not
been associated with sevoflurane anesthesia.
23. • Alkali such as barium hydroxide lime or soda
lime (but not calcium hydroxide) can degrade
sevoflurane producing another proven ( at
least in rats) nephrotoxic end product
(compound A), accumulation of compound A
increases with increased respiratory gas
temperature, low flow anesthesia, dry barium
hydroxide absorbent (baralyme), high
sevoflorane concentrations, and anesthetics of
