Comparison of Spontaneous Ventilation, Pressure Control Ventilation and Pressure Support Ventilation in Pediatric Patients Undergoing Infraumbilical Surgery Using ProSeal Laryngeal Mask Airway.

Background: Pediatric infraumbilical surgeries are often performed under general anaesthesia using different modes of ventilation through Laryngeal Mask Airway .Although controlled ventilation has been successfully used, very less studies have been done to compare them with spontaneous ventilation for short duration surgeries.

Aims: We tried to measure quantitave differences in haemodynamic and respiratory parameters and assess the recovery profile between controlled and spontaneous ventilation using Proseal LMA.

A Comparative Study of Epidural Anesthesia with Dexmedetomidine Infusion versus General Anesthesia for Percutaneous Nephrolithotomy.

Background: There has been considerable debate regarding the ideal anaesthetic technique for Percutaneous Nephrolithotomy (PCNL). PCNL is usually performed under general anaesthesia (GA) in prone position. The prone position under GA is associated with various complications.

A randomized double-blind study to evaluate efficacy and safety of epidural magnesium sulfate and clonidine as adjuvants to bupivacaine for postthoracotomy pain relief.

Background: The aim of the study was to compare postoperative pain relief in patients undergoing an elective thoracotomy with thoracic epidural analgesia using single shot magnesium and clonidine as adjuvants to bupivacaine.

Methods: In a randomized prospective study, 60 patients of American Society of Anesthesiologists physical status I-III of either sex, between 20 and 60 years undergoing elective unilateral thoracotomy, were allocated to three equal groups of 20 patients. Each patient received thoracic epidural analgesia using bupivacaine alone (Group A) or with magnesium (Group B) or clonidine (Group C) at the end of surgery during skin closure.

A prospective, randomized, double blind study to compare the effects of equiosmolar solutions of 3% hypertonic saline and 20% mannitol on reduction of brain-bulk during elective craniotomy for supratentorial brain tumor resection.

Aims: The aim of the study was to compare the effect of mannitol (M) and hypertonic saline (HTS) on brain relaxation and electrolyte balance.

Settings And Design: Prospective, randomized, double-blind study.

Subjects And Methods: A total of 114 patients with American Society of Anesthesiologists status II and III, scheduled to undergo craniotomy for supratentorial brain tumor resection were enrolled.
