A Preliminary Feasibility Study on Hemodynamic Changes Following Feyh-Kastenbauer Retractor Insertion During Transoral Robotic Surgeries.

 Introduction Transoral robotic surgery (TORS) has become increasingly popular for the removal of pharyngeal and laryngeal cancers with the objective to improve functional and aesthetic outcomes. Feyh-Kastenbauer (FK) retractor is one such routinely used retractor during TORS. The setting up of this retractor has been seen to be accompanied by hemodynamic fluctuations.

Measurement of bupivacaine induced myotoxicity in interfascial plane blocks: A randomised controlled trial.

Background And Aims: Recent reports of local-anaesthetic induced myotoxicity after peripheral nerve blocks have increased interest in this less commonly known complication. Although the morphological, physiological and biochemical changes in muscle after injection of clinically used concentration of bupivacaine have been studied in animals, little research has been conducted on human subjects, especially in relation to fascial plane blocks. We conducted a study to examine the changes in circulating creatine phosphokinase (CPK) levels in patients undergoing modified radical mastectomy (MRM) or mesh hernioplasty (MH) with or without peripheral nerve blocks.

A randomised study comparing the extent of block produced by spinal column height and body weight-based formulae for paediatric caudal analgesia.

Background And Aims: Height and weight-based formulae are used for calculation of dose of medications for caudal analgesia but these have not been compared. We compared spinal column height-based Spiegel and weight-based Takasaki and Armitage formulae for achieving maximum height of sensory neuraxial block after caudal epidural analgesia in paediatric patients.

Methods: In this double-blind randomised study, children aged between 1 and 6 years and planned for infra-umbilical surgery were randomly allocated to receive caudal epidural block (targeting Tlevel block) with 0.
