Randomized Controlled Trial Comparative Study Clinical TrialComparison of local infiltration of tenoxicam and intravenous tenoxicam for postoperative analgesia in herniorrhaphy.
The major complaint of herniorrhaphy is postoperative pain which occurs during the first 24 h after operation. Tenoxicam has a long half-life of 60-80 h. Local infiltration of the drug concentrates the pain control effects in the local area. The local infiltration dose can be smaller than the recommended systemic dose needfully to reach the target area to be effective. Therefore we studied the effect of preoperative local infiltration of tenoxicam on postoperative pain. ⋯ Preoperative local infiltration of tenoxicam can decrease postoperative pain score significantly during the most painful period (24 h) in herniorrhaphy.

Randomized Controlled Trial Clinical TrialEffect of BL-10 (tianzhu), BL-11 (dazhu) and GB-34 (yanglinquan) acuplaster for prevention of vomiting after strabismus surgery in children.
Stimulation of P6 (Neiguan) acupoint can prevent nausea and vomiting in adults. However, there is no antiemetic effect in children undergoing strabismus surgery. The effect of P6 may act only on hollow organs; in contrast, BL-10 (Tianzhu), BL-11 (Dazhu) and GB-34 (Yanglinquan) are more related to the meridians of the eye. Therefore these three more relevant acupoints, BL-10, BL-11 and GB-34 were stimulated to evaluate the antiemetic effect in children undergoing strabismus surgery. ⋯ The results demonstrated that prophylactic use of bilateral noninvasive acuplaster on the BL-10, BL-11, and GB-34 acupoints significantly reduces vomiting after strabismus correction. The mechanism may be dispersal of these three acupoints, thus diminishing the parasympathetic stimulation resulting from surgical traction of eye muscles.

Case ReportsManipulation of epidural catheter that has migrated restores adequate postoperative analgesia--a case report.
The use of epidural anesthesia and analgesia is ordinary in patients undergoing total knee replacement (TKR). As many as 23% of epidural anesthetics may not provide satisfactory analgesia for women in labor. ⋯ We reported a case in whom the in-place epidural catheter which functioned well for surgical anesthesia previously migrated to an intervertebral foramen postoperatively and led to failure of providing post-operative analgesia. With deliberate manipulation we succeeded in restoring its function and analgesia showed up again.

Randomized Controlled Trial Comparative Study Clinical TrialProspective and randomized trial of intravenous tenoxicam versus fentanyl and tramadol for analgesia in outpatient extracorporeal lithotripsy.
As extracorporeal shock wave lithotripsy (ESWL) is frequently carried out on an outpatient basis, it is crucial to choose an adequate analgesic with less adverse effect. This study evaluated the use of three different intravenous agents: fentanyl, tramadol HCl and tenoxicam in ESWL. ⋯ Lithotripsy can be satisfactorily performed by employing fentanyl, tramadol or tenoxicam for analgesia; tenoxicam apparently offers a better analgesic quality with less side effect. Furthermore, the need for stronger analgesia during larger voltage intensity should be tailored to the needs of the individuals.

Case ReportsVentricular tachycardia after oxytocin injection in patients with prolonged Q-T interval syndrome--report of two cases.
Oxytocin is widely used in obstetric settings to stimulate uterine contraction and prevent postpartum hemorrhage. Its adverse effects which include transient hypotension and increase heart rate could be life-threatening in patients with fixed cardiac output or hypotension resulting from hemorrhage. We reported two cases suspected to have preexisting prolonged Q-T interval syndrome (PQTS) who developed ventricular tachycardia immediately after intravenous injection of oxytocin. Anesthetic management of and use of oxytocic agents in patients with PQTS were discussed.
