Filter by:The goal of this clinical trial is to compare the effectiveness of PCA ketamine-morphine versus conventional PCA morphine in postoperative patients undergoing elective laparotomy colorectal surgery under general anaesthesia. The specific objectives are: 1. To compare the post-operative analgesic requirement with PCA ketamine-morphine in comparison with PCA morphine. 2. To compare the postoperative pain scores between PCA ketamine-morphine and PCA morphine. 3. To assess patients' overall satisfaction with PCA ketamine-morphine in comparison with PCA morphine. 4. To study the incidence of side effects of PCA ketamine-morphine in comparison with PCA morphine. Participants will be screened and recruited at pre-anaesthetic clinic (PAC). Those who consented will be taught to use PCA machine and the potential side effects of the study drugs. They will be randomly allocated into either Group A or Group B by computer generated randomization a day before planned surgery. Researchers will compare Group A and Group B to see post-operative pain scores, patients' overall satisfaction and any incidence of side effects.

Perioperative multimodal analgesia, defined by the use of various analgesic medications targeting different drug receptors, provides adequate pain relief with minimal or no opiate consumption. Therefore, it represents one of the cornerstone of Enhanced Recovery After Surgery (ERAS) protocols, as the reduction in opioid use and the associated side effects may eventually reduce length of hospital stay, increase patient satisfaction and minimise the risk of long-term opioid use. Regional and neuraxial anesthesia techniques are key interventions to provide successful analgesia in the context of a multimodal strategy. Intrathecal morphine, for its effectiveness and potential of reducing the need of intravenous postoperative opioids, seems an attractive option in the case of hysterectomy, one of the most common major surgical procedures performed in women, associated with severe postoperative pain even when performed laparoscopically. The aim of our observational retrospective study is therefore to compare the analgesic efficacy and the safety of morphine administered by intrathecal route versus intravenous route during the first 48 hours after performance of laparoscopic/laparotomic hysterectomy.
The aim of this study is to the effect of opioid (morphine) intradermal application on histaminergic and non-histaminergic itch. In particular, we would like to demonstrate that also peripheral administration of morphine may affect mast cell release of histamine.
: Spine surgery induced severe postoperative pain. Several techniques as intravenous multimodal analgesia have been proposed to reduce pain relief and morphine rescue over the first postoperative days. Regional anesthesia using the erectus nerve block is a simple infiltration across lamina of the vertebra: Ultrasound-guided posterior ramus of spinal nerve block for anesthesia and analgesia in lumbar spinal surgery This study compared erector nerve block with local anesthetic vs placebo to reduce pain and morphine rescue after lumbar spine surgery. The investigators hypothesized that eructor nerve block induced a large block from L1 to L5 that induced posterior nerve roots block anesthesia. This block reduced pain after surgery.
The purpose of this study is to show that the effect of 3% 2-chloroprocaine prior to epidural morphine administration will be not inferior to the effect of epidural 2% lidocaine with 1:200,000 epinephrine on total opioid use for 24h
In This experiment, the investigators would like to test the two following hypotheses regarding the mechanisms by which opioids cause itch: 1. Opioids cause itch by a spinal disinhibition mechanism (central nervous system (CNS) effect). 2. Opioids cause itch through a mast cell-destabilizing effect leading to release of histamine and tryptase in the skin where itch is evoked (peripheral mechanism).
The main objective of the trial is to investigate the effect of known genetic variants in organic cation transporter 1 (OCT1) on the effect of morphine after major surgery
The investigators want to investigate the effect of low dose S+ ketamine compared to placebo on cumulative morphine consumption at 24 hours in 90 women undergoing open abdominal hysterectomy with remifentanil-propofol target controlled infusion (TCI) in KK Women's and Children's Hospital. The secondary aims are to investigate the use of low dose S+ ketamine on the incidence of nausea, vomiting, pruritus (opioid side effect), sedation score and psycho mimetic assessment compared to placebo group. The investigators propose to conduct a double blinded, randomized controlled study in women undergoing open abdominal hysterectomy with remifentanil-propofol TCI. (1) Treatment Group: intravenous ketamine 0.5 mg/kg at the beginning and 0.5 mg/kg 20 minutes before extubation. (2) Control Group: intravenous normal saline (as placebo) at the beginning and 20 minutes before extubation.
The purpose of this study is to determine which postoperative analgesia is optimal after colorectal surgery. The investigators will compare intrathecal morphine, continuous epidural analgesia and standard systemic analgesia. All patients will have the possibility to administer themselves intravenous morphine as needed.
