Background At Sri Balaji Vidyapeeth, a competency-based learning and training (CoBaLT©) model for postgraduate (PG) curriculum, within the regulatory norms, was implemented in 2016 after adequate faculty development programmes. This focused on well-defined outcomes. Methods A review of the outcomes was undertaken in 2018 as part of internal quality assurance receiving feedback from all stakeholders, viz.

Background: Real-time ultrasound guidance (USG) has been applied for lower thoracic epidural access, but the more challenging mid-thoracic epidural (MTE) access remains underexplored. This report presents a technique of real-time US guidance with a novel paramedian cross view, termed "the PX view," for securing MTE catheters, along with an outcome analysis from a retrospective case series.

Methods: Medical records of patients who underwent USG-MTE catheter placement with the PX view and drip infusion technique from January to December 2022 were reviewed.

Background And Aims: Posterior-transversus abdominus plane (TAP) block and transversalis fascia plane (TFP) block have been used for postoperative analgesia following caesarean delivery. We compared the analgesic efficacy of the TAP vs TFP plane blocks in patients undergoing elective caesarean delivery.

Methods: We randomised 90 women undergoing caesarean delivery under spinal anaesthesia to receive either a posterior-TAP (Group-TAP), TFP (Group-TFP) or no block (Group-C) postoperatively.

Introduction: Recent evidence has questioned the advantage of local anesthetic (LA) combinations. This study tested the hypothesis that mixing rapid-onset (lidocaine) and long-duration (bupivacaine) LA would provide faster onset of complete conduction blockade (CCB) compared with bupivacaine alone and longer duration of analgesia compared with lidocaine alone during low-volume (20 mL) ultrasound-guided (USG) supraclavicular brachial plexus block (SCBPB).

Methods: Sixty-three patients receiving USG-SCBPB were randomly allocated into: group : 20 mL 2% lidocaine with epinephrine 1:200 000; 20 mL 0.

Background: Significant collapsibility during spontaneous respiration, deeper location, and smaller vein size are key challenging factors to safe infraclavicular axillary vein cannulation. Arm abduction reduces collapsibility, but interventional data supporting this observation is lacking. This study investigates the effect of neutral and abducted arm position on the first pass success rate of infraclavicular axillary vein cannulation in spontaneously breathing patients.

Background And Aims: Commonly, the superficial cervical plexus and interscalene block were combined to provide surgical anaesthesia for procedures on the clavicle, which are neither selective nor site-specific considering the innervation of the clavicle. The aim was to analyse effectiveness and block dynamics of selectively blocking supraclavicular (SC) nerves and upper trunk (UT) of brachial plexus (SCUT BLOCK) as a site-specific regional anaesthesia strategy for clavicle surgery.

Methods: SC nerves and UT were blocked with 3-ml and 5-ml local anaesthetic, respectively, in 70 American Society of Anesthesiologists I and II patients aged above 18 years, undergoing clavicle surgery.

Background And Aims: Brachial plexus (BP) blocks continue to be described with reference to anatomical landmarks (Interscalene and Supraclavicular), even after the introduction of ultrasound which enables us to directly identify the roots, trunks and divisions of the BP. The aim of this study was to describe a novel injection technique targeting trunks of BP and to determine the minimum effective local anaesthetic volume (MELAV) required to produce BP block with this approach.

Methods: Twenty-one male patients in the age group 20-40 years, undergoing elective forearm bony procedures received an ultrasound-guided truncal injection BP block.

Background: Abduction of the arm has been used for ultrasound-guided infraclavicular axillary vein cannulation. We evaluated the influence of arm position on sonographic visualization and cannulation of the axillary vein in patients receiving mechanical ventilation.

Methods: Sixty patients scheduled to undergo surgery under general anaesthesia with controlled mechanical ventilation were included in this prospective randomized study.

Background: The costoclavicular brachial plexus block (BPB) produces faster onset of sensory motor blockade than the lateral sagittal approach. However, the incidence of phrenic nerve palsy (PNP) after a costoclavicular BPB is not known.

Objectives: The current study compared the incidence of ipsilateral hemidiaphragmatic paresis, and thus PNP, between a supraclavicular and costoclavicular BPB.

Background: Several video laryngoscopes had demonstrated their superiority over conventional oral and nasal intubation techniques. King Vision video laryngoscope has fewer studies supporting its suitability for oral intubations. However, its suitability as a nasal intubating device has not been yet evaluated.

Background: Quality of postoperative analgesia after cesarean section makes difference to mother in child bonding, early ambulation, and discharge. Ilioinguinal iliohypogastric (ILIH) and transverse abdominis plane (TAP) block had been tried to reduce the opioid analgesics, but the relative efficacy is unknown. Hence, this study was designed to compare the efficacy of these two regional analgesic techniques in sparing postoperative rescue analgesic requirement following lower segment cesarean section (LSCS).

Background: Visualization of vocal cords following extubation after thyroid and major neck surgeries is highly desirable for the surgeon as well as the anaesthesiologist to rule out vocal cord palsy or oedema. As the patient is emerging from general anaesthesia, it may be challenging for the anaesthesiologist to optimally visualise and grade vocal cord movement following extubation.

Setting: Randomized clinical trial at a tertiary care centre.

Background: Fentanyl and dexmedetomidine have been tried to attenuate airway and circulatory reflexes during emergence and extubation individually but have not been compared with respect to the level of sedation to evolve a reliable technique for rapid and smooth extubation.

Aim: To compare the effects of fentanyl and dexmedetomidine in attenuating airway and circulatory reflexes during emergence and extubation of the endotracheal tube.

Setting And Design: This double-blind, randomized, controlled study was done in patients undergoing surgery under general anesthesia belonging to the American Society of Anesthesiologists physical status 1 or 2.

Background And Objectives: The optimal site for local anesthetic injection during an ultrasound-guided supraclavicular brachial plexus block (BPB) is not known. We tested the hypothesis that local anesthetic injected deep to the "brachial plexus sheath" during supraclavicular BPB would produce faster onset of surgical anesthesia than an injection superficial to the sheath.

Methods: After research ethics approval and informed consent, 32 patients undergoing upper-extremity surgery under an ultrasound-guided supraclavicular BPB were randomly assigned to receive 25 mL of a 1:1 mixture of 2% lidocaine with 1:200,000 epinephrine and 0.

We present a case of a 40-year-old male patient who presented to us with radicular pain in arm for anterior cervical discectomy with fusion. The preanesthetic checkup including indirect laryngoscopy was normal with routine investigations within normal limits. The patient was induced and intubated with the established routine technique without any obvious airway problems.

Background: Applying appropriate positive end-expiratory pressure (PEEP) to corresponding intra-abdominal pressure (IAP) can improve gas exchange during capnoperitoneum without any hemodynamic effects.

Materials And Methods: A total of 75 patients were randomly allocated to group 0PEEP (n=25), group 5PEEP (n=25), and group 10PEEP (n=25) according to the level of PEEP, in whom capnoperitoneum was created with IAP of 14, 8, and 14 mm Hg, respectively. Hemodynamic and respiratory parameters were recorded up to 30 minutes after capnoperitoneum.
