The efficacy of ultrasound-guided upper thoracic erector spinae plane block for postoperative analgesia in proximal shoulder surgery and its effect on phrenic nerve function: A prospective exploratory study.

Background And Aims: The upper thoracic (T2) erector spinae plane block (UT-ESPB) has been proposed as an alternative to interscalene brachial plexus block for postoperative analgesia in shoulder surgery. The current study was conducted to evaluate the same.

Material And Methods: Patients scheduled for shoulder surgery under general anesthesia (GA) received ultrasound-guided UT-ESPB.

Efficacy of lignocaine nebulization in patients with COVID-19 respiratory infection: An exploratory randomized double-blinded controlled trial.

Background And Aims: Coronavirus disease (COVID-19)-related pneumonia is proposed to be an inflammatory process. The treatment currently includes supportive therapy and low-dose steroids. Anti-inflammatory drugs have been proposed to prevent cytokine storms and improve oxygenation in such cases.

A randomised trial comparing block characteristics of a mixture versus sequential injections of lignocaine and ropivacaine for supraclavicular brachial plexus nerve block in patients undergoing upper limb surgery.

Background And Aim: There is no consensus on the appropriate use of mixtures of local anaesthetic drugs in various combinations for nerve blocks. We intended to compare short-acting lignocaine and long-acting ropivacaine as a mixture versus undiluted sequential injections on block characteristics of ultrasound-guided (USG) supraclavicular brachial plexus block for upper limb surgeries.

Methods: A double-blinded randomised study was conducted on 64 adult patients scheduled for upper limb surgery who received 15 mL each of 2% lignocaine with adrenaline and 0.

Comparison of block characteristics and outcomes in opioid-free and opioid-based thoracic continuous spinal anaesthesia in patients undergoing major abdominal surgery: A double-blinded randomised controlled trial.

Background And Aims: Thoracic continuous spinal anaesthesia (TCSA) is emerging as the sole anaesthetic for major abdominal surgery due to its better perioperative outcomes. This study was designed to evaluate block characteristics and outcomes in 'opioid-free' and 'opioid-based' TCSA.

Methods: After ethical approval, trial registration and written informed consent, 50 adult patients undergoing major abdominal surgery were randomised into 'opioid-free' (bupivacaine alone) and 'opioid-based' (bupivacaine with fentanyl) groups.

Recovery time in target controlled infusion versus manual infusion of propofol in total intravenous anaesthesia for endoscopic retrograde cholangio-pancreatography procedure using laryngeal mask airway-gastro: A randomised comparative study.

Background And Aims: This study aimed to compare manual infusion versus target-controlled infusion (TCI) in total intravenous anaesthesia (TIVA) utilising laryngeal mask airway (LMA)-gastro during endoscopic retrograde cholangio-pancreatography (ERCP) procedures.

Methods: This was a single-blind randomised trial. Patients were randomly allocated into two groups.

Use of a human patient simulator for apnea studies: a preliminary in vitro trial.

Background: Modern human patient simulators (HPSs) could be used for researching critical scenarios such as apnea oxygenation. We aimed to study the use of a high-fidelity HPS to assess prolonged apnea using various oxygenation strategies with a simple high-flow nasal cannula (15 L/min).

Methods: An experimental simulation study using an HPS (CAE Healthcare™) was conducted after obtaining approval from the Institutional Review Board.

Comparative efficacy of supraclavicular versus infraclavicular approach of subclavian vein cannulation under ultrasound guidance: A randomised clinical trial.

Background And Aims: Subclavian vein (SCV) cannulation can be performed using either supraclavicular (SC) or infraclavicular (IC) long-axis approach under ultrasound guidance (USG). However, their relative efficacy remains debatable. The aim of this study was to compare these two approaches in terms of safety, ease, success rate, and record the incidence of complications.

Accuracy of non-invasive haemoglobin measurements in patients undergoing transurethral resection of prostate surgery.

Background And Aims: The aim of this study was to evaluate the accuracy of non-invasive haemoglobin (SpHb) compared to laboratory venous haemoglobin (tHb) measurements among patients undergoing elective transurethral resection of prostate (TURP) surgery under spinal anaesthesia.

Methods: In a prospective, observational, outcome-assessor blinded, cohort trial, we enroled 50 American Society of Anesthesiologists physical status (ASA-PS) I-II patients with benign prostatic hyperplasia. The primary outcome included SpHb and tHb measurements performed at four perioperative time-points: just before initiating the fluid preload (T1), and at 30 min (T2), 1 h (T3), and 2 h (T4) after starting the prostate resection, respectively.

Comparison of landmark versus pre-procedural ultrasonography-assisted midline approach for identification of subarachnoid space in elective caesarean section: A randomised controlled trial.

Background And Aims: Identification of subarachnoid space in pregnant patients can pose a great challenge to anaesthesiologists. This study was designed to compare conventional landmark technique with pre-procedural ultrasonography-assisted midline approach for identification of the subarachnoid space in elective caesarean section.

Methods: After institute ethics committee approval and written informed consent, 100 parturients scheduled for elective caesarean section under spinal anaesthesia were included in this prospective randomised control trial and divided into Group L ( = 50) (landmark technique) and Group U ( = 50) (ultrasound-guided technique).

A comparative study of nerve stimulator versus ultrasound-guided supraclavicular brachial plexus block.

Introduction: With the advent of ultrasound (US) guidance, this technique saw resurgence in the late 1990s. As US guidance provides real-time view of the block needle, the brachial plexus, and its spatial relationship to the surrounding vital structures; it not only increased the success rates, but also brought down the complication rates. Most of the studies show use of US guidance for performing brachial plexus block, results in near 100% success with or without complications.

Intubating condition, hemodynamic parameters and upper airway morbidity: A comparison of intubating laryngeal mask airway with standard direct laryngoscopy.

Background: Intubating Laryngeal Mask Airway (ILMA) is a relatively new device designed to have better intubating characteristics than the standard Laryngeal Mask Airway. This study was designed to compare Intubating Laryngeal Mask with standard Direct Laryngoscopy (DLS), taking into account ease of intubation, time taken for intubation, success rate of intubation, hemodynamic responses and upper airway morbidity.

Materials And Methods: Sixty patients, ASA I or II, of age between 20 and 60 years, were enrolled in this prospective and randomized study.
