Ultrasonographic evaluation of diaphragmatic excursion changes after major laparoscopic surgeries in the Trendelenburg position under general anaesthesia: A prospective observational study.

Background And Aims: Laparoscopic surgeries result in increased intra abdominal pressure and cephalad displacement of the diaphragm. The Trendelenburg position can augment these respiratory changes. The primary objective of this study was to compare diaphragmatic excursions before and after a major laparoscopic pelvic surgery under general anaesthesia in the Trendelenburg position using ultrasonography (USG).

Retrospective analysis of patients with severe maternal morbidity receiving anaesthesia services using 'WHO near miss approach' and the applicability of maternal severity score as a predictor of maternal outcome.

Background And Aims: Risk stratification of severely morbid obstetric patients receiving anaesthesia services can be helpful in improving maternal outcomes. This study was undertaken to analyse these patients using the WHO near-miss (NM) approach and to assess the applicability of maternal severity score (MSS) to predict maternal mortality.

Methodology: This is a one-year retrospective cohort analysis at a tertiary care centre.

Comparative evaluation of i-gel insertion conditions using dexmedetomidine-propofol versus fentanyl-propofol - A randomised double-blind study.

Background And Aims: i-gel insertion necessitates adequate depth of anaesthesia to prevent laryngospasm, gagging or limb movements. We aimed to compare i-gel insertion conditions with propofol induction after pre-treatment with dexmedetomidine or fentanyl.

Methods: Eighty ASAI/II patients undergoing general anaesthesia were randomised into Groups D ( = 40) and F ( = 40).

Effect of Pneumoperitoneum and Lateral Position on Oropharyngeal Seal Pressures of Proseal LMA in Laparoscopic Urological Procedures.

Introduction: A sustained and effective oropharyngeal sealing with supraglottic airway is required to maintain the ventilation during laparoscopic surgery. Previous studies have observed the Oropharyngeal Seal Pressure (OSP) for Proseal Laryngeal Mask Airway (PLMA) after pneumoperitoneum in supine and trendelenburg position, where PLMA was found to be an effective airway device. This study was conducted with ProSeal LMA, for laparoscopic Urologic procedures done in lateral position.

Comparison of Dexmedetomidine-Propofol versus Fentanyl-Propofol on Insertion Conditions of Proseal Laryngeal Mask Airway.

Introduction: Proseal Laryngeal Mask Airway (PLMA) is a newer supraglottic airway device that requires adequate depth of anaesthesia and suppression of upper airway reflexes thereby providing optimal insertion conditions.

Aim: To compare dexmedetomidine and fentanyl for co-induction with propofol with respect to PLMA insertion conditions, haemodynamic variation and the total dose requirement of propofol.

Materials And Methods: This was a prospective randomized double-blinded study conducted in 60 cases of American Society of Anaesthesiologists (ASA) class I/II undergoing elective surgery under general anaesthesia.
