Clinical TrialSpontaneous intraoperative hypothermia and cerebral protection in aneurysmal subarachnoid hemorrhage.
In patients with aneurysmal subarachnoid hemorrhage (SAH), a trend towards cerebral protection has been demonstrated with intraoperative mild hypothermia. Mild to moderate spontaneous hypothermia occurs intraoperatively if no active measures are taken to warm the patient. The present study investigated the cerebral protective role of such spontaneous intraoperative hypothermia in patients with aneurysmal SAH. ⋯ The findings of the current study suggest that mild spontaneous intraoperative hypothermia offers cerebral protection in patients undergoing surgery for aneurysmal subarachnoid hemorrhage. This protective role of seems to be related to the anatomical location of the aneurysm.

Comparative StudyPressure measurements during cardiac surgery--internal jugular vs central venous.
Although central venous pressure (CVP) is a valuable guide and measurement during cardiac surgery anesthesia, there are many occasions however, when the time consumed in inserting a peripheral catheter, defeats the actual purpose. The purpose of this study was to compare central venous pressure and internal jugular veins pressure, and to see whether the jugular veins pressures were a reliable guide to central venous pressure monitoring. Simultaneous measurements of the internal jugular (both left and right side) and right atrial venous pressures were made in 70 patients undergoing cardiac surgery both at times when the chests were closed and when they were opened. ⋯ Then the CVP and internal jugular veins were measured six times during anesthesia and postoperatively. A good correlation was found between pressures of right and left internal jugular veins with that of CVP both at times when the chests were closed and when they were opened. It is concluded that left and right internal jugular vein pressures are reliable guides to central venous pressures during anesthesia in cardiac surgery.

Regional analgesia combined with avoidance of narcotics may reduce the incidence of postoperative vomiting in children.
The anesthesia literature cites a high incidence of postoperative vomiting (POV) after pediatric ochidopexy and hernia repair (34-50%) and after penile procedures (37-49%). We hypothesized that regional analgesia combined with avoidance of narcotics administered to children scheduled for lower abdominal or urologic procedures may be associated with a lower incidence of POV. The aim of this prospective study was to 1) assess the incidence of POV in children in the hospital and during a 24-h post-anesthesia study period, and 2) evaluate the effect of age on POV. ⋯ We concluded that regional analgesia combined with the avoidance of narcotics administered to children scheduled for elective urologic or lower abdominal procedures, is associated with a lower incidence of POV and that age did not affect the incidence of POV.

Comparative StudyPredictor of sedation during endoscopic retrograde cholangiopancreatography--bispectral index vs clinical assessment.
The bispectral index (BIS) has been developed as a monitor of sedation in patients receiving anesthetic and sedative drugs. BIS has been shown to correlate with responsiveness under sedation and anesthesia with a variety of agents. This study was designed to compare BIS with clinical assessment of sedation during ERCP. ⋯ These results imply that BIS may be a valuable monitor for safe level of sedation and operator's satisfaction during ERCP.

Quality improvement in anesthetic practice--incidence of sore throat after using small tracheal tube.
Sore throat following surgery is common and is due to multitude of factors. The highest incidence of sore throat tends to occur in patients who have undergone tracheal intubation. Between 14.4% to 50% of intubated patients complain of sore throat and hoarseness in the immediate postoperative period, 3% of them are still hoarse after a week. This contributes to higher incidence of postoperative morbidity and patient dissatisfaction of the service. A prospective study was conducted to demonstrate the incidence of hoarseness and sore throat following the use of small tracheal tubes. ⋯ The use of small tube in intubating the trachea, together with other measures such as lubricating the tube with water soluble jelly, careful airway instrumentation, intubation only when patient was fully relaxed, careful suctioning technique, and extubation when the tracheal tube cuff was fully deflated, have dramatic effects on minimizing the incidence of postoperative hoarseness and sore throat. Accordingly, patient satisfaction has been reported to be high.
