Clinical Observation of Changing Rulse Rate during Induction of Pediatric General Anesthesia with Halothane and Nitrous Oxide / 대한마취과학회지

The author observed pulse rate change in various conditions of halothanenitrous oxide general anesthesia i.e. before premedication, before anesthesis, after intubation and before operation in 200 anesthetic cases of children aging from birth to 16 years old at department of anesthesia of K.U.H. since last 3 years. The following results were obtained, 1. It revealed increased pulse rate after premedication than before and particularly, group A was more remarkable in all groups. 2. It revealed slight decreased pulse rate after intubation. 3. It revealed decreased pulse rate at surgical stage of anesthesia, but pulse rate was increased comparing with before premedication in all groups. 4. The younger, the more variable pulse rate were obtained from ward by administering of drugs or anesthesia in all groups.

Tension Pneumothorax during General Anesthesia / 대한마취과학회지

Tension pneumothorax occurred in a 42 year old man with pulmonary tuberculosis during induction of general anesthesia for left lobectomy. Rupture of emphysematous bullse, presumably due to positive pressure ventilation employed during induction, was identified by immediate thoracotomy. The patient made an uneventful recovery.

Clinical Observation of Blood Pressure Changes During Spinal Anesthesia / 대한마취과학회지

In an attempt to observe the influence of the spinal anesthesia on the systolic blood pressure, 350 cases of the spinal anesthesia ranging from 16 to 60 years of age were analyzed. The spinal anesthetics in this study was hyperbaric solution of 0.5% tetracaine in 6 or 10% D/W. The 350 cases were put into 4 groups by their preanesthetic systolic blood pressure and by post anesthetic dermatome of sensory block, and then the alteration of blood pressure in systolic of each group was studied. The results obtained are as follows. 1) The maximal fall of blood pressure was seen at 10 min. after spinal anesthesia. 2) Of the groups of the same sensory block dermatome, the fall of the more prominent in the higher initial systolic blood pressure group. 3) Of the groups of the same initial systolic blood pressure, the fall of was more prominent in the higher sensory block dermatome group. 4) The most prominent fall of the systolic blood pressure during spinal anesthesia was seen on the highest sensory block dermatome and initial systolic blood pressure.

A Case of General Anesthesia for a Patient of Congenital` Esophageal Atresia with Tracheo-esophageal Fistula / 대한마취과학회지

The authors have experienced a case of general anesthesia for a patient of congenital esophageal atresia with tracheo-esophageal fistula. Paramount importance of particular attention to the maintenance of patent airway and the removal of secretions whenever necessary for the patient's safety throughout anesthetic and postonesthetic period has been stressed. General anesthetics which irritate the respiratory tract and increase secretions must be avoided. Keeping the patient in an incubator with oxygen and humidity after anesthesia is recommended. In case of respiratory distress due to gastric dilatation, gastrostomy under local anesthesia before operation may be helpful.
