Case Reports[Obstetrical analgesia in a woman allergic to ethylene oxide].
A case is reported of a 28 year old woman, with untreated mitral valve disease and a professional allergy to ethylene oxide and phthalic anhydride, who presented with acute hydramnios during the 35th week of pregnancy. Emergency caesarean section having been decided on, a urinary catheter--sterilized by gamma rays and not ethylene oxide--was inserted; the gloves used had however been sterilized in ethylene oxide gas, and the patient rapidly presented with anaphylactic shock. ⋯ Caudal anaesthesia with 0.25% bupivacaine was used to complete the spinal analgesia and speed up cervical dilation. The child was delivered with forceps and the diagnosis of oesophageal atresia was confirmed.

Randomized Controlled Trial Clinical Trial[Prolongation of spinal anesthesia with hyperbaric bupivacaine by adrenaline and clonidine in the elderly].
So as to determine the effects of vasoconstriction on the duration of hyperbaric bupivacaine spinal anaesthesia, a prospective controlled study was carried out on 80 ASA class II or III patients, aged 75 years or more, who were scheduled for spinal anaesthesia for lower limb surgery. They were randomly allocated to four groups, and were each given 3 ml (15 mg) of 0.5% bupivacaine in plain solution with 0.5 ml of 30% dextrose solution, together with 1 ml normal saline in group I, 0.15 mg clonidine in group II, 0.2 mg adrenaline in group III, and 0.4 mg adrenaline in group IV. All patients therefore received 4.5 ml of 0.33% bupivacaine solution in 3.3% dextrose solution. ⋯ Regression times tended to increase more with 0.4 mg than with 0.2 mg adrenaline. Significant prolongation of motor block was also associated with the addition of vasoconstrictors. It is concluded that addition of 0.15 mg clonidine or 0.4 mg adrenaline may be useful to increase duration of hyperbaric bupivacaine spinal anaesthesia in elderly patients.
