ProSeal laryngeal mask airway (PLMA) efficacy in pediatric anesthesia. ⋯ Both PLMA size 2 and 2½ provided adequate seal pressures that would allow positive pressure ventilation in healthy children. Thus PLMA of either size 2 or 2½ can be used as a reliable airway device in children weighing 20-30 kg.

Midazolam and clonidine are preferred premedicants whose effects are not restricted to the preoperative period. In addition, these premedicants significantly modulate not only the intraoperative requirements of the anesthetic agents, but also the postoperative outcome. We aim to compare the efficacy of both the agents in view of premedication, induction characteristics, hemodynamic changes and postoperative complications utilizing bispectral index (BIS) using propofol anesthesia. ⋯ Both clonidine and midazolam contributed equally in lowering propofol consumption. Reduction in the induction dosage of propofol and hemodynamic variations were also observed to be similar with the use of midazolam or clonidine as premedicants. Both provide a beneficial effect in relation to recovery and less postoperative complications. However clonidine premedication was found to be more effective in preventing post operative shivering and can be recommended in routine practice.

Difficult tracheal intubation contributes to significant morbidity and mortality during induction of anesthesia. There are divided opinions regarding ease of intubation in obese patients. Moreover, the definition of difficult intubation is not uniform; hence we have use the Intubation Difficulty Scale (IDS) to find the incidence of difficult intubation in obese patients. ⋯ Obese patients are difficult to mask ventilate and intubate. During intubation of obese patients who is more than 40 years age and SMD <12.5 cm, it is preferable to have a second skilled anesthesiologist.

The present study aimed to compare the efficacy of injectable diclofenac intramuscularly (IM), injection paracetamol intravenously (IV), or a combination of both to provide post-operative analgesia in patients undergoing lower abdominal gynecological surgeries. ⋯ Injection diclofenac IM is more effective than paracetamol IV in terms of rescue analgesic requirement, but the combination of diclofenac IM and paracetamol IV provides no added advantage over diclofenac IM alone.

Postoperative nausea and vomiting is commonly associated with adverse consequences and hamper the postoperative recovery in spite of the availability of many antiemetic drugs and regimens for its prevention. The study was aimed to compare the prophylactic effects of intravenously administered palonosetron, ondansetron, and granisetron on prevention of postoperative nausea and vomiting after general anesthesia. ⋯ Palonosetron was comparatively highly effective to prevent the PONV after anesthesia due to its prolonged duration of action than ondansetron and granisetron.
