Intraoperative low-dose ketamine infusion for postoperative pain relief in laparoscopic surgeries – A randomised, double blind controlled clinical trial
Background: Patients undergoing laparoscopic surgery often experience moderate-to-severe postoperative pain. The use of opioids for postoperative pain relief often results in respiratory depression and other adverse effects. Hence, we studied the effect of ketamine infusion administered at a low…

Comparison of effects of volume-controlled equal inspiratory-to-expiratory ratio (1:1) ventilation with conventional ratio (1:2) ventilation on respiratory mechanics and hemodynamics in patients undergoing upper abdominal laparoscopic surgeries: A randomized clinical trial
Background: Patients undergoing laparoscopic surgeries are often at risk of developing hypoxemia, increased airway pressure, and barotrauma due to pneumoperitoneum. Prolongation of inspiratory time in a respiratory cycle has been found to improve oxygenation without any increase in peak airway…

Anaesthetic Course in a Rare Case of Lupus Vasculitis Presenting as Mononeuritis Multiplex for Caesarean Section
The term mononeuritis multiplex (MNM) complex is used to describe myriad groups of disorders that share a common presentation characterized by painful, multifocal, asymmetrical peripheral neuropathy affecting sensory and motor nerves. Vasculitic origin accounts for most multifocal neuropathy…

Neuraxial anaesthesia in a parturient with space occupying lesion in brain for caesarean section: Demystifying the myth – A case report with review
Pregnancy makes a patient undergo diverse physiological changes and predisposes them to many pathological disorders such as pre-eclampsia, eclampsia, cortical vein thrombosis, and pituitary apoplexy. Any intervention during pregnancy presents a unique challenge as it affects two individuals. Once…

Comparison of Haemodynamic Effects of Intravenous Carbetocin Versus Oxytocin for the Prevention of Postpartum Haemorrhage in Patients Undergoing Caesarean Section Under Subarachnoid Block: A Double-Blind Randomised Controlled Trial
Background and Aims: Atonic PPH remains one of the most common causes of mortality among patients undergoing caesarean section. Oxytocin continues to be the first-line uterotonic but has undesirable effects due to its extrauterine receptor action. Carbetocin, a newer oxytocin analogue, has a better…

Comparison of Postoperative Analgesia Between Intrathecal Nalbuphine and Intrathecal Fentanyl in Infraumbilical Surgeries: A Double-Blind Randomized Controlled Trial
Introduction: Spinal anesthesia is a widely used regional anesthesia technique for surgeries below the umbilicus, but postoperative analgesia is of major concern due to the relatively short duration of the local anesthetic. Various drugs were used as an additive to local anesthetic to prolong the…

A case of successful management of perioperative pulmonary embolism
Acute pulmonary embolism (PE) is a relatively common complication after major orthopedic surgeries with a high mortality rate. We present a case of L4–L5 disc prolapse with radiculopathy posted for spinal instrumentation and fusion surgery who developed PE perioperatively. It was diagnosed…

Utility of thoracic segmental spinal anaesthesia (TSSA) in high-risk surgical patients – our experience: Twin case report
Thoracic segmental spinal anesthesia (TSSA) is a relatively older technique with renewed interest in recent years due to utilization by an increasing number of anesthesiologists across the globe. It is considered as a suitable alternative to general anesthesia (GA) in surgical patients who are…

Assessment of Pressure Support Ventilation versus T-Piece Ventilation in Spontaneous Breathing Trials for Successful Extubation in Mechanically Ventilated Patients: A Open-labelled Block Randomised Controlled Trial
Introduction: Spontaneous Breathing Trials (SBTs) are vital in determining readiness for extubation in patients undergoing mechanical ventilation. Pressure Support Ventilation (PSV) and T-piece ventilation are two commonly used methods for conducting SBTs. Aim: To compare the rates of weaning…

A case of perioperative myocardial infarction leading to asystole: An anesthesiologist's nightmare
Perioperative myocardial infarction (PMI) in patients without a prior history of coronary artery disease is quite rare. Diagnosing PMI is also quite challenging because of a myriad of events mimicking MI during the perioperative period. we are reporting of PMI leading to cardiac arrest which was…

To determine the efficacy of intrathecal dexmedetomedine and fentanyl as adjuvants to spinal anesthesia for lower abdominal surgeries below the level of umbilicus - A prospective randomized controlled double blinded study
Background: Spinal anesthesia is widely used regional anesthesia technique; however, postoperative analgesia is a major problem. The duration of analgesia can be prolonged by the addition of intrathecal adjuvants. Hence, this study is aimed to assess the characteristics of spinal block between the…

Effect of Magnesium Sulphate and Dexmedetomidine on Blood Loss during Lumbar Spinal Fusion Surgeries
Introduction: Spine surgeries pose unique challenges to the anaesthesiologist in maintaining stable haemodynamics, relatively dry operative field and concerns over patient positioning during surgery. Aim: The present study was aimed at comparing the effect of magnesium sulphate and Dexmedetomidine…

A Randomised Controlled Study of Two Different Doses of Bupivacaine in Ultrasound Guided Axillary Brachial Plexus Block
Introduction: The use of Ultrasound (USG) for needle precision aids in reduction of local anaesthetic volume needed for peripheral nerve blockade. Conventional dosages of 30 to 40 mL of local anaesthetic mixture have been used in peripheral nerve blockades but using a lesser volume will reduce the…
