Tetrology of Fallot (TOF) is the most commonly encountered congenital cardiac lesion in pregnancy. Although there are controversies regarding safe anesthetic technique for parturient with TOF, we use low-dose sequential combined-spinal epidural anesthesia in such a case posted for Cesarean section and found that low dose (0.5 ml of 0.5%) intrathecal bupivacaine and fentanyl with sequential epidural bupivacaine supplementation was adequate for the performance of an uncomplicated Cesarean section with minimal side effects and good fetal outcome. Thus, though the choice of anesthesia can vary in such patients, low-dose sequential combined-spinal epidural can be a safe alternate to achieve good anesthesia with impressive cardiovascular stability.

THE AIM OF THE PRESENT STUDY WAS TO COMPARE THE ABILITY TO PREDICT DIFFICULT VISUALIZATION OF THE LARYNX FROM THE FOLLOWING PREOPERATIVE AIRWAY PREDICTIVE INDICES, IN ISOLATION AND COMBINATION: modified Mallampati test (MMT), the ratio of height to thyromental distance (RHTMD) and the Upper-Lip-Bite test (ULBT). ⋯ The RHTMD is comparable with ULBT for prediction of difficult laryngoscopy in general population.

Propofol is a commonly used short-acting intravenous anaesthetic agent. A major disadvantage of propofol is pain at injection site with high incidence up to 90%. Various modalities have been tried to obtund propofol-induced pain; however, search for an ideal agent continues. We assessed the effect of double and triple dilution of 1% propofol emulsion with normal saline on pain at injection site. ⋯ We found a significant decrease in both incidence and severity of pain during injection with a 0.33% propofol solution without significant adverse hemodynamic effects. The small size of data was a limitation in our study and a large-scale study will be needed to prove its therapeutic beneficence.

Negative pressure pulmonary edema (NPPE) is a dangerous and potentially fatal condition with a multifactorial pathogenesis. Frequently, NPPE is a manifestation of upper airway obstruction, the large negative intrathoracic pressure generated by forced inspiration against an obstructed airway is thought to be the principal mechanism involved. ⋯ The early detection of the signs of this syndrome is vital to the treatment and to patient outcome. The purpose of this review is to highlight the available literature on NPPE, while probing the pathophysiological mechanisms relevant in both the development of this condition and that involved in its resolution.
