Postoperative recovery of arterial oxygen saturation determined by pulse oximetry in pediatric patients.
Small children are physiologically subject to arterial oxygen desaturation. However, few reports have referred to the risk factors related to postanesthetic hypoxemia and the duration of hypoxemia. The purpose of this study was to clarify these two aspects. ⋯ Age, height, and weight of these 10 children were significantly different from the remaining 75, but there were no significant differences in anesthetic duration and postanesthetic awakefulness between the group with postanesthetic hypoxemia and the one without. The importance of monitoring the clinical condition of pediatric patients after general anesthesia is universally acknowledged. Monitoring with the pulse oximeter has proven very useful and shows that, unless oxygen saturation is monitored, all children should receive supplemental oxygen.

Report on the computer software contest at the 39th Congress of the Lapan Society of Anesthesiology.
We held another computer software contest at the 39th Congress of the JSA. The aim and procedure were similar to those for the first contest in 1991. Twenty-four softwares entered the contest; the machines are divided approximately two to one ratio between NEC PC9801 series and Macintosh. ⋯ They were given away to those who made entries for the contest. Most of these programs have been registered as free softwares at various computer networks. A plan is under way to distribute them in diskette forms.

Blood pressure, heart rate and catecholamine response during fiberoptic nasotracheal intubation under general anesthesia.
Arterial blood pressure (ABP) and heart rate were recorded at one-minute intervals during several stages of intubation in the fiberscope group and the laryngoscope group, to determine if fiberoptic nasotracheal intubation would result in fewer hemodynamic and catecholamine responses than when intubation was performed with a Macintosh laryngoscope. Blood samples were also taken to measure plasma catecholamine concentration immediately after intubation with the fiberscope. The mean ABP in the laryngoscope group was slightly greater than that of the fiberscope group for 4 min after intubation. ⋯ Other cardiovascular complications were more common in the laryngoscope group than in the fiberscope group. These results suggest that fiberoptic intubation results in less severe stress than does laryngoscopic intubation. Fiberoptic intubation should therefore be used not only in patients with difficult airway, hypertension, ischemic heart disease, or cerebrovascular atherosclerosis, but also it is recommended for all patients for whom nasotracheal intubation is indicated.

Effects of tilting in the sagittal plane on the cephalad spread of anesthesia.
The effect of tilting in the sagittal plane on the spread of anesthesia was studied in 30 healthy male patients. Two ml of 0.3% hyperbaric dibucaine was used for intrathecal injection in the lateral position. After 3 min of resting on their side, 15 patients were placed in the horizontal supine position. ⋯ There was no significant difference in the mean cephalad spread of the analgesic level in the dependent side between the two groups. Unilateral motor anesthesia of the dependent side seemed to be canceled by the sagittal tilting maneuver. A 7 to 8 degree tilt in the sagittal plane is recommended to facilitate the cephalad spread of analgesia and to avoid unilateral anesthesia.
