To study the change of maternal pulmonary function when ropivacaine and bupivacaine were used in spinal anesthesia for cesarean section, 40 ASA physical status I and II parturient scheduled to undergo cesarean section were randomly divided into bupivacaine and ropivacaine groups. Bupivacaine 9 mg and ropivacaine 14 mg were intrathecal injected respectively. FVC, FEV1 and PEFR were measured with spirometry before anesthesia and 2 h after intrathecal injection. Anesthesia level, the degree of motor block and VAS were also recorded. ⋯ Decreases in maternal pulmonary function tests were similar following spinal anaesthesia with bupivacaine or ropivacaine for cesarean section. The clinical maternal effects of these alterations appeared negligible.

To introduce a new modified technique for radial artery catheterization. ⋯ The authors suggested the use of 1 ml hollow tube-assisted radial artery cannulation technique rather than a direct technique. This modified technique provided easy, safe, quick and less cost cannulation.

Sedation with propofol is widely used for the outpatient examination. Although anaphylaxis to propofol is rare, there were some reports of anaphylaxis following propofol administration. We present a case of female patient under sedation for lower gastrointestinal endoscopy with possible propofol anaphylaxis. ⋯ Propofol is widely used for the sedation of outpatient with lower gastrointestinal endoscopy. But it may cause some allergic reaction. Inhaled sevoflurane may provide a satisfactory and safe alternative for adult outpatients' endoscopy.

To compare the cost-effectiveness of inhalation of sevoflurane, target-controlled infusion (TCI) of propofol, intravenous (IV) propofol for induction-inhalation of sevoflurane, and IV propofol for induction-inhalation of desoflurane for anesthesia maintenance in day surgery. ⋯ Induction with intravenous injection of propofol and maintenance with inhalation of desoflurane is the most cost-effective method of anesthesia for day surgery.

Case Reports
Surgical treatment and radiotherapy of epidermoid cyst with malignant transformation in cerebellopontine angle.
We report surgical treatment and radiotherapy of an extremely rare case of malignant epidermoid cyst located in cerebellopontine angle. MRI and CT demonstrated the lesion with partial enhancement and calcification. During operation, we found the tumor attached tightly to surrounding tissue. ⋯ With adjuvant radiotherapy, the patient underwent excellent recovery, and follow-up MRI demonstrated no obvious residue or recurrence of the tumor. Malignant epidermoid cyst can be diagnosed radiologically in combination with clinical presentation. Maximal removal plus adjuvant radiotherapy is the treatment of choice, although the general prognosis of it is poor.
