Postoperative Pain Management and the Risk Factors in Major Operation: A Baseline Study of Acute Pain Service, Siriraj Hospital.

Background: Acute pain service (APS) has been set up at Siriraj Hospital with the aim of providing postoperative pain management for patients receiving anesthetic pain control and other complicated cases undergoing major operations.

Objective: To identify the incidence of moderate to severe postoperative pain and its risk factors. To describe the techniques used and adverse effects in patients under APS care.

The effect of epidural low-dose morphine-soaked microfibrillar collagen sponge in postoperative pain control after laminectomy and instrumented fusion: a randomized double-blind placebo-controlled study.

Objective: To evaluate the postoperative analgesic effect and postoperative nausea and vomiting (PONV) after using epidural low-dose morphine-soaked microfibrillar collagen sponge (MMCS), as compared with placebo.

Material And Method: A prospective randomized double-blind placebo-controlled study was performed on patients under-going single-level posterior lumbar spinal decompression and instrumented fusion at the Department of Orthopedic Surgery, Siriraj Hospital, between August 2012 and December 2013. Patients were randomly allocated into two groups to receive either an epidural MMCS or an epidural normal saline-soaked microfibrillar collagen sponge (placebo).

Low-dose spinal morphine for post-thoracotomy pain: a prospective randomized study.

Objective: To compare the results of 0.2 mg and 0.3 mg of spinal morphine in patients with post-thoracotomy pain.

Clinical characteristics of spinal levobupivacaine: hyperbaric compared with isobaric solution.

We performed a prospective, double-blinded study in 20 patients undergoing gynecologic surgery with lower abdominal incision, to investigate characteristics of intrathecal hyperbaric levobupivacaine compared with isobaric levobupivacaine. We randomly assigned them to receive 3 mL of either isobaric or hyperbaric 0.42% levobupivacaine intrathecally.

Postoperative analgesic effects of intravenous lornoxicam and morphine with pre-emtive ropivacaine skin infiltration and preperitoneal instillation after transabdominal hysterectomy.

Unlabelled: To investigate the effectiveness of intravenous lornoxicam and morphine with the preemptive effects of ropivacaine local skin infiltration and peritoneal instillation in reducing postoperative pain after transabdominal hysterectomy, a randomized, double blinded, placebo-controlled study was done in 88 patients undergoing transabdominal hysterectomy under general anesthesia. The patients were allocated into 4 groups to receive: (group A) only intravenous morphine 10 mg; (group B) intravenous morphine 10 mg and lornoxicam 16 mg; (group C) intravenous morphine 10 mg, lornoxicam 16 mg with 0.5 per cent ropivacaine local skin infiltration before skin incision and 1 per cent ropivacaine instillation before peritoneal incision; (group D) intravenous morphine 10 mg, lornoxicam 16 mg with 1 per cent ropivacaine instillation after peritoneal closure and 0.

Effectiveness of lightwand (Trachlight) intubation by 1st year anesthesia residents.

Transillumination of the soft tissue of the neck using a lighted stylet (lightwand) is an effective and safe intubating technique in experienced hands. The goal of this study was to determine the effectiveness and safety of this device in intubating the trachea of elective surgical patients by non-experienced hands. One hundred and fifty, paralysed, anesthetized, adult patients (ASA I-II, no known or potential problems with intubation) were studied.

Starting intravenous morphine in the postanesthesia care unit yielded better postoperative analgesia.

The administration of morphine intravenously in the Postanesthesia Care Unit (PACU) was practiced in many parts of the world, but not routinely done in Thailand. This prospective randomized controlled trial was performed to reassure Thai personnel that this practice was safe, to find the optimum dose of morphine for administration in the PACU, and to find the pain level at which patients needed no more analgesics. Eighty gynecological patients, ASA class I or II, were randomly allocated into two groups.

Adding droperidol to morphine patient-controlled analgesia: effect on nausea and vomiting.

This prospective, double-blind, randomized, controlled trial was performed to evaluate the antiemetic effectiveness and side effects of adding droperidol to morphine delivered via a patient-controlled analgesia (PCA) device in 94 women undergoing transabdominal hysterectomy with a standardized anesthetic regimen. They were randomly allocated to receive postoperative PCA as either bolus doses of morphine I mg or a combination of morphine 1 mg and 0.0625 mg droperidol with a lockout interval of 5 minutes and no continuous infusion.
