Randomized Controlled Trial Comparative Study
[Effects of intravenous vasopressor on spread of spinal anesthesia with 0.5% hyperbaric bupivacaine for caesarean delivery].
It is known that when isobaric bupivacaine is applied for Caesarean delivery, phenylephrine is superior to ephedrine in preventing rostral spread of spinal anesthesia. In this study, we prospectively investigated whether phenylephrine can prevent rostral spread of spinal hyperbaric bupivacaine. ⋯ 1. Phenylephrine prevented rostral spread of spinal hyperbaric bupivacaine. 2. Haemodynamic changes were significantly different between the two groups. 3. Umbilical artery pH was significantly higher with phenylephrine than with ephedrine.

We experienced two cases of anaphylaxis during anesthesia using rocuronium in two months. In both cases, we carried out intradermal test and positive reaction occurred with rocuronium. In both cases, the second anesthesia without neuromuscular blockade was uneventful. Though it is difficult to diagnose anaphylaxis, we should suspect anaphylaxis when cardiovascular collapse, bronchospasm and/or dermal symptoms occur after induction of anesthesia.

We report a pregnant woman who developed non-traumatic spinal subdural and epidural hematoma. A 31-year-old woman at 28 weeks of gestation developed progressive ascending paralysis. ⋯ An emergency cesarean section followed by spinal decompression was performed 60 hours after the onset. The patient's neulogical function recovered completely after the surgey.

A 34-year-old woman who was 25 weeks pregnant showed neurological symptoms of bitemporal hemianopsia and vision loss on the left side. MRI study revealed a pituitary tumor requiring surgical removal. We planned cesarean section after 32 weeks of pregnancy and removal of pituitary tumor after the improvement of general conditions of the paturient following cersarean section. ⋯ Therefore, we decided to perform the cesarean section at 30 weeks and 3 days of pregnancy and simultaneous surgical removal of the pituitary tumor. As soon as cesarean section was successfully performed with epidural anesthesia, the pituitary tumor was removed trans-sphenoidally under general anesthesia. Postoperative conditions of the mother and newborn were good and neurological symptoms of the mother improved markedly.

The i-gel, invented by Muhammed Aslam Nasir, is a new supraglottic airway, consisting of a mask and a tube. One notable feature of the i-gel is that the rim of the mask is designed to conform to the anatomical shape of the larynx. This enables the device to provide an airtight seal without the cuff mechanism. ⋯ No airway complications occurred during the anesthesia, and spontaneous breathing could be maintained. No blood was detected on the device, after uneventful removal in all the patients. We believe that the i-gel is useful in maintaining a clear airway during general anesthesia.
