Comparison of recovery characteristics with two different washout techniques of desflurane anaesthesia: A randomised controlled trial.

Background: Rapid emergence with low soluble inhalational agents (IA) is offset by a significant association with emergence agitation (EA). Research on the influence of elimination methods of IA on recovery characteristics is very few. We conducted this study to compare the recovery characteristics of slow elimination (SE) of desflurane with purging technique.

Prophylactic norepinephrine infusion or leg wrapping for postspinal hypotension in elective caesarean delivery: A randomised, double-blind, placebo-controlled trial.

Background: Because of its alpha and beta agonist properties, norepinephrine infusion is currently being studied for the prevention of spinal hypotension during caesarean delivery. Vasopressor infusions are not always possible if there is an unavailability of infusion pumps. Leg wrapping with crepe bandage is an effective technique for prevention of postspinal hypotension and could be useful in resource-poor settings.

Quantifying influence of epidural analgesia on entropy guided general anaesthesia using sevoflurane - A randomised controlled trial.

Background And Aims: Minimum alveolar concentration (MAC) of inhalational agent denotes the requirement of it to maintain adequate plane of general anaesthesia. The precision to the maintenance of anaesthesia can be further guided by use of entropy to titrate the depth of anaesthesia. Regional anaesthesia and the concomitant deafferentation will decrease the need of general anaesthetics.

Sonographic visualization and cannulation of the axillary vein in two arm positions during mechanical ventilation: A randomized trial.

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.

Arm position and collapsibility of infraclavicular axillary vein during voluntary breathing: An ultrasound-guided observational study.

Background: Arm abduction influences cross-sectional area of the infraclavicular axillary vein, yet the effect of arm abduction on collapsibility of the vein has not been quantified. Decrease in collapsibility of the axillary vein can enable successful cannulation and can decrease injury to underlying vital structures.

Methods: The infraclavicular axillary vein was scanned in 70 patients close to the clavicle with a high-frequency linear transducer in arm adducted position (Point A), after arm abduction at the initial probe position (Point A') and after tracing the vein medially close to clavicle (Point B).

Subarachnoid block with continuous TAP catheter analgesia produces less chronic pain and better functional outcome after inguinal hernioplasty: a randomized controlled observer-blinded study.

Background And Objectives: The major concern after inguinal hernioplasty is chronic postsurgical pain and impaired quality of life due to central sensitization. Preoperative, intraoperative, and postoperative pre-emptive analgesia using regional techniques may help prevent the development of central sensitization. This study evaluated the effect of regional anesthesia followed by continuous regional analgesia on postoperative pain and functional outcome following inguinal hernioplasty.
