188 patients including 30 young adults and 158 old patients were successfully given spinal anesthesia with meperidine at doses of 1.2 - 1.4mg/kg -1b.w for surgery of the lower abdomen, peritoneal areas and the lower extremities. Mean duration of actions of spinal Meperidine were 80.56±12.75 minutes in young and old patients, respectively. There was no big difference of side effects of the spinal meperidine between these two groups of patients

In view of the current trend towards carrying out termination of pregnancy as day cases it is also important that the patient should be free from pain with a rapid recovery from anesthesia and a minimum of post operative sequalae. We compared the effects of three other anesthetic techniques for the termination of pregnancy in 100 healthy womes as day cases. 1) Anesthesia with thiopental sodium alone was associated with a high score of pain sensation(2+/-0.93) and with considerably rapid recovery(103+/-57.6 mins). 2) The combination of thiopental sodium and meperidine was associated with a lower score of pain sensation(1.58+/-0.8) and with rapidl recovery(101+/-56.4 mins). 3) Meperidine with diazepam was associated with the lowest score of pain sensation(1.4+/-0.69), but had prolonged recovery time(206+/-126 mins) twice that of other techniques. It was conclued that the combination A thiopental sodium and meperidine was the technique of choice for termination of pregnancy as day-cases.

Adequate pain relief is a requisite for a successful closed manipulative reduction (CMR) of fractures and dislocations. This prospective study was undertaken to assess the mode and adequacy of pain relief given to patients undergoing such procedures at Seremban Hospital from the 1st April to the 31st May 2001. All patients with fractures and dislocations scheduled to undergo CMR were included in this study. The type of sedative agents and analgesia administered were recorded. Demographic data and the type of fracture or dislocation of the selected patients were documented. A visual analogue scale (VAS) for pain perception was given to both to the patients and the medical personnel who performed the procedure. All data were collected manually before entered into computerized database for analysis. Of 72 patients included in this study, 47% were Malay, 26% Indian, 21% Chinese and 6% others. There was male predominance and the patients' age ranged between 9 to 79 years (average 27.4 years). Upper limb injuries (79%) were mainly fractures of the radius and ulna (29%) and isolated fracture radius (21%). For the lower limb injuries (21%), combined tibia and fibula fractures constituted 10% of the total cases followed by isolated tibia fractures (10%) and hip dislocation (1%). The most common pain relieving agents given during the CMR were intravenous pethidine alone (43%) followed by combination of intravenous pethidine and valium (36%), intramuscular pethidine (17%) and intramuscular tramal (4%). The Visual Analogue Score (VAS) for pain perception revealed that 61% of the patients had moderate pain while 21% had severe pain during the course of the procedures. Suboptimal pain relief administered during CMR should prompt positive actions to ensure that the patient is not subjected to undue pain just for the sake of an acceptable fracture reduction.

BACKGROUND: Although early reviews of clinical findings were mostly negative, there is still a widespread belief for the efficacy of preemptive analgesia among clinicians. In this study, we evaluated whether the preemptive use of ketamine decreases post operative pain in patients undergoing appendectomy. METHODS: In double-blind, randomized clinical trials, 80 adult male patients undergoing an operation for acute appendicitis were studied. Patients were randomly assigned to two groups. In the operating room, patients in the ketamine group received 0.5 mg/kg of ketamine IV 10 minutes before the surgical incision. In the control group, 0.5 mg/kg of normal saline was injected. The pain intensity was assessed at time 0 (immediately after arousal) and 4, 12, and 24 hours postoperatively using the 10 points visual analogue scale (VAS). RESULTS: Eighty patients (40 for both groups) were enrolled in this study. For all of the evaluated times, the VAS score was significantly lower in the ketamine group compared to the control. The interval time for the first analgesic request was 23.1 +/- 6.7 minutes for the case group and 18.1 +/- 7.3 minutes for the control (P = 0.02). The total number of pethidine injections in the first 24 hours postoperatively was 0.6 +/- 0.6 for the case group and 2.0 +/- 0.8 for the controls (P = 0.032). There were no drug side effects for the case group. CONCLUSIONS: A low dose of intravenously administered ketamine had a preemptive effect in reducing pain after appendectomy.

It has recently been reported that chemical evaluations of a new benzodiazepine derivative, flunitrazepam (Ro 5-4200) revealed promising effects as premedicant. We studied on effects of premedication by double blind technique comparing flunitrazepam (Ro 5-4200) 0.03mg/kg I.M. and meperidine HCI 1mg/kg I.M. in 300 cases of preoperative patient by random selection. The questionaire on drowsiness, sleepiness and awareness during transport to the operation theatre, as well as nausea and vomiting were checked by anesthetists who were ignorant of the given premedicant. Following results were obtained; 1) Flunitrazepam has excellent calming effects in preanesthetic period, inducing drowsiness and adequate rest. 2) Flunitrazepam produces good sleep the night before operation. 3) Flunitrazepam has lower incidence of nausea and vomiting than that cf meperidine HCI.

Severe muscular rigidity is a rare but potentially serious side effect from the use of opioid, usually in high dose. However it has also been reported with the use of low to moderate dose of opioids in a few occasions. The age of the patients varied from newborn to old. These diverse and unpredictable natures of clinical manifestations seem to be related to the unknown mechanisms in the subcortical areas which are difficult to study. Now the author reports the case of severe muscular rigidity which occurred in the 5 year old child who received the usual analgesic dose of meperidine, notably in rapid injection. And after reviewing the related literatures,the author puts some emphasis regarding management of this problem.
