The use of succinylcholine for rapid sequence induction in patients with open globe injuries may be detrimental to the eye. ⋯ MgSO4 30 mg/kg as well as 50 mg/kg effectively prevented the rise in IOP, MAP, and HR associated with rapid sequence induction by succinylcholine and endotracheal intubation.

The Proseal LMA(PLMA), which has been designed especially for positive pressure ventilation and protection against aspiration can act as an alternative to Endotracheal Tube (ETT) as an effective airway device for patients undergoing elective Laparoscopic surgeries. ⋯ A properly positioned PLMA is a suitable and safe alternative to ETT for airway management in adequately fasted, adult patients undergoing elective Laparoscopic surgeries.

Transsphenoidal approach to pituitary tumors is a commonly performed procedure with the advantage of a rapid midline access to the sella with minimal complications. It may be associated with wide fluctuations in hemodynamic parameters due to intense noxious stimulus at various stages of the surgery. As duration of the surgery is short and the patients have nasal packs, it is prudent to use an anesthestic technique with an early predictable recovery. ⋯ A continuous intravenous infusion of dexmedetomidine as compared to oral clonidine improved hemodynamic stability in patients undergoing transnasal transsphenoidal resection of pituitary tumors.

Enlarged thyroid gland with retrosternal extension has an increased incidence of difficult intubation, and it poses real airway challenge for the anesthesiologists. Here, we present a case of successful management of a difficult airway in a female patient of enlarged thyroid gland, planned for open reduction and internal fixation of the upper end of humerus. Endotracheal intubation was achieved after deliberate insertion of an endotracheal tube in esophagus. The patient was extubated over a ventilating bougie, with uneventful postoperative course.

This study aims to compare the minimum effective concentration of local anesthetic (LA) bupivacaine and ropivacaine with highly lipid soluble opioids fentanyl for providing optimal labor epidural analgesia. ⋯ In our study, both the drugs produced equivalent analgesia for labor at low concentration when used with highly lipid soluble opioid such as fentanyl.
