A case of 30 year-old female with HELLP syndrome, who had undergone emergency caesarean section under general anesthesia, was reported. HELLP syndrome is characterized by hemolysis, liver dysfunction and thrombocytopenia, besides symptoms of severe toxemia of pregnancy. ⋯ Though the eclampsia was recognized several times during and after the operation, the patient and her baby had no complication nor sequela on their discharge. The key in the anesthetic management of caesarean section in a patient with HELLP syndrome is to control hypertension and eclampsia, to consider the presence of liver and kidney dysfunctions, and to improve anemia and bleeding tendency.

The supraclavicular brachial plexus block originated by Kulenkampff is useful but accompanies the danger of injury to the lung, i.e. pneumothorax, because the needle is directed caudad. Reviewing the anatomy of the brachial plexus in cadavers, we have found that the parascalene brachial plexus block originated by Vongvises is safer than Kulenkampff's method. We modified this block as follows: (1) An assistant pulls lightly the affected upper extremity caudad. (2) A 23-gauge 35 mm needle is inserted at right angles to the clavicle and directed cephalad at an angle of 0-30 degrees. ⋯ Our success rate was 92%. The only complication we encountered was Horner's syndrome which occurred in 20% of our cases. None of our patients showed clinical symptoms of pneumothorax, hematoma, epidural as well as subarachnoideal block, recurrent nerve paralysis or phrenic nerve paralysis.

The laryngeal mask is a unique alternative to the face mask and endotracheal tube offering significant benefits to both anesthesiologist and patient. We have applied laryngeal mask, 1) to create an adequate airway in cases of difficult or impossible intubation, 2) to establish a pathway for the fiberoptic bronchoscope, 3) to clear the airway for eye operation, and 4) to maintain the airway in patients in the lateral position. Further study, however, is necessary to establish definite indication for its application.

Transesophageal echocardiography (TEE) has been used as a monitor of cardiovascular function and as a diagnostic tool in anesthetic practice. TEE is the only available monitor to detect anatomical abnormalities such as of wall motion as well as valvular abnormalities. Doppler TEE has wider diagnostic functions. ⋯ There are, however, several shortcomings such as its cost, "too much sensitivity", requirement of some experience, interobserver variability, and so on. The computer-assisted on-line analysis would greatly augment usefulness of TEE. When these shortcomings are overcome, TEE would be one of the most important monitors in anesthetic practice.

Comparative Study
[A comparison of hemodynamic changes with sufentanil-O2 and fentanyl-O2 anesthesia for coronary bypass grafting].
Hemodynamic changes were investigated in twenty patients undergoing coronary artery bypass grafting. Thirteen patients received sufentanil-O2 anesthesia and seven patients had fentanyl-O2 anesthesia. Systolic, diastolic, as well as mean arterial blood pressures, heart rate and rate pressure product (RPP) were measured before and after intubation, one minute after skin incision, and one minute after sternotomy. ⋯ Diastolic pressure was not significantly changed in each group. Stable hemodynamic parameters with no ST-T change were noticed during surgical procedure in each group. We conclude that sufentanil is a superior narcotic agent than fentanyl for the patients undergoing CABG, and it effectively blocks sympathetic reflex activity.
