Randomized Controlled Trial Clinical TrialIntravenous tenoxicam reduces dose and side effects of PCA morphine in patients after thoracic endoscopic sympathectomy.
Among surgical modalities for treatment of palmar hyperhidrosis, endoscopic sympathectomy is the most popular choice in recent years. After surgery, the major complaint was anterior chest pain. This study was conducted to evaluate the analgesic efficacy and side effects of tenoxicam (a thienothiazine derivative) in combination with patient-controlled analgesia (PCA) using morphine in patients who received thoracic endoscopic sympathectomy. ⋯ Tenoxicam may be an effective adjuvant to PCA morphine for postoperative pain control. This combination reduces the total consumption of PCA morphine with less side effects.

Randomized Controlled Trial Clinical TrialAnalgesic effect of intra-articular morphine after arthroscopic knee surgery in Chinese patients.
Small or systematically inactive doses of morphine administered into the knee joint during intra-articular surgery can elicit potent and long-lasting postoperative analgesia. The reports studied in USA, Spain, UK, Germany, Ireland, etc. showed that intra-articular morphine 0.5-5 mg could produce a significant analgesic effect with an onset time of 0-6 h after administration and a duration of 24-48 h. However, there were no available data about the Chinese people; therefore, this study was designed to collect the data regarding this subject. ⋯ We concluded that intra-articular morphine 1 mg in Chinese patients could provide an effective and long-lasting analgesic effect, which was quite similar with the result presented in other races.

Mannitol increases cerebral arteriovenous oxygen difference in patients undergoing craniotomy.
Monitoring the jugular venous oxygen saturation (SjVO2) and cerebral arteriovenous oxygen difference (AVDO2) is valuable in detecting cerebral ischemia. In the present study, we investigated the effect of mannitol on SjVO2 and AVDO2 in patients undergoing craniotomy. ⋯ Mannitol may produce a further reduction in SjVO2 accompanied by an increase in AVDO2, suggesting a reduction of cerebral blood flow (CBF) during hyperventilation. Therefore, it should be given cautiously in neurosurgical patients under hyperventilation.

[The blood pressure of upper and lower extremities in parturients under spinal anesthesia for cesarean section].
In clinical practice, we only measure the blood pressure of the arm during cesarean section. However, it can not accurately reflect the real image of pressure of the lower extremity in labor women. Therefore, we recorded simultaneously the arm and leg blood pressure in the term parturients undergoing cesarean section under spinal anesthesia. ⋯ We suggest that monitoring blood pressure in cesarean section under spinal anesthesia should be minute to minute for the first ten minutes and one had best monitor the lower extremity blood pressure in order to promptly detect hypotension.
