Comparative efficacy of postoperative analgesia between ultrasound-guided dual transversus abdominis plane and Ilioinguinal/Iliohypogastric nerve blocks for open inguinal hernia repair: An open label prospective randomised comparative clinical trial.

Background And Aims: Transversus abdominis plane (TAP) and Ilioinguinal/Iliohypogastric (IL/IH) nerve blocks have been advocated in reducing postoperative pain and additional analgesic requirement following lower abdominal surgeries with varied effect. The aim of this study was to determine post-operative analgesic efficacy by comparing dual TAP [combining TAP and IL/IH nerve blocks] and IL/IH nerve block alone for open inguinal hernia repair.

Methods: Two hundred patients undergoing elective primary unilateral open inguinal hernia repair with a mesh were included in to this trial.

Hemi-diaphragmatic paresis following extrafascial versus conventional intrafascial approach for interscalene brachial plexus block: A double-blind randomised, controlled trial.

Background And Aims: Hemidiaphragmatic paresis occurs in almost all patients undergoing interscalene block for proximal upper limb surgeries. This study tested hypothesis that ultrasound-guided extrafascial approach of interscalene block under nerve stimulator guidance reduces incidence of hemidiaphragmatic paresis in comparison to intrafascial approach by achieving same degree of anaesthesia and analgesia.

Methods: Sixty patients undergoing proximal upper limb surgeries were randomised to receive an ultrasound-guided interscalene brachial plexus block (ISB) with the aid of nerve stimulator for surgical anaesthesia and analgesia using 20 mL 0.

Comparison between perivascular and perineural ultrasound-guided axillary brachial plexus block using levobupivacaine: A prospective, randomised clinical study.

Background And Aims: Ultrasound (US)-guided regional blocks are becoming increasingly popular as its use increases success rate, shortens block onset time and reduces complications. Currently, there exist two methods to perform US-guided axillary brachial plexus block (US-ABPB), the perivascular (PV) and the perineural (PN) techniques. We compared the two techniques to study the block characteristics and other variables using levobupivacaine.

"Comparative efficacy of different doses of fentanyl on cardiovascular responses to laryngoscopy and tracheal intubation".

Background: This study was conducted to determine an effective bolus dose of fentanyl, which would attenuate the cardiovascular response to laryngoscopy and tracheal intubation.

Materials And Methods: A randomised double blind controlled study was carried out on 50 healthy adult patients (ASA I and II) undergoing elective surgery under general anaesthesia. The patients were randomly allocated into two groups of 25 each i.
