Filter by:This study aimed to evaluate the effect of epidural patient-controlled analgesia (PCA) on postoperative pain relief after lumbar spine surgeries. The eligible patients received two types of postoperative pain management: PCA and standard pain treatment. Comparisons between the two groups were made in terms of postoperative pain level.
Primary aim is to compare the effectiveness of the posterior approach Transversus abdominis plane block (P-TAP) and the lateral approach Transversus abdominis plane block (L-TAP) technique on the pain management of the laparoscopic nephrectomy in terms of visual analog pain scale and postoperative opioid consumption. Secondary aim is to compare complication rates of the two techniques.
To explore the effect of different drugs and infusion ways on degree of postoperative comfort.Patients undergoing spinal neoplasm surgery receive different patient controlled analgesia(PCA) drugs postoperatively,one group is sufentanil,the other is hydromorphone. Then each drug group will be divided into two subgroups according to the infusion way,intravenously,subcutaneously. During the patient controlled analgesia period, patients' degree of comfort,pain score,sleep quality, the degree of side reaction will be recorded.
If the individual patient's pain is assessed and the amount of analgesic needed after surgery is predicted, appropriate injection of pain control and excessive injection of narcotic analgesic can be prevented. Therefore, investigators try to evaluate the degree of pain during surgery and the amount of analgesic use for management of postoperative pain.
Opioids via intravenous patient-controlled analgesia (IV PCA) are widely used for postoperative pain control. However, effective pain control with minimized side effects of analgesic agents is still challenging. Several studies reported that preoperative pain sensitivity measured by quantitative sensory test could predict postoperative pain. Therefore, the investigators planned this trial to evaluate the effectiveness of tailored patient-controlled analgesia based on preoperative pain sensitivity measured by pressure pain threshold in patients undergoing gynecological surgery.
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.
Introduction Ketamine is an old and generally well accepted analgesic used in the intra- and perioperative setting. Several studies demonstrated the effectiveness of ketamine in the postoperative setting. A new formulation of S-ketamine as an intranasal spray device was tested in our hospital in 8 healthy volunteers (unpublished data, EKBB 351/08). 20 mg of S-ketamine were administered intranasally and compared with S-ketamine i.v. and i.m.. None of the volunteers had serious adverse effects or complications. A preliminary data analysis shows a clear analgesic effect and good absorption of the intranasal S-ketamine. As a next step we would like to investigate the effect of S-ketamine intranasal spray combined with midazolam intranasal spray in a group of postoperative spinal surgery patients. The rational for the combination of intranasal S-ketamine and midazolam is the well known midazolam antagonising effect of ketamine induced psychomimetic adverse effects. Furthermore we know from other studies (EKBB 106/06) that midazolam intranasal spray has relaxant and anxiolytic effects. As far as we know, this is the first study which will examine the combination of S-ketamine and midazolam intranasal sprays in adult patients. Study work plan This prospective, randomized, double-blinded non inferiority study will address pain ratings and patient satisfaction in a postoperative setting in two treatment scenarios: 1. Alternating S-ketamine intranasal unit-dose spray (6 mg per dose) with midazolam intranasal spray (0.75 mg per dose) patient controlled application with a lock-out interval of 20 minutes between two applications and placebo patient controlled analgesia (PCA) with a lock-out interval of 12 minutes with saline 0.9% i.v. for 72 hours or until 40 unit-dose sprays are delivered 2. PCA with 2 mg morphine with a lock-out interval of 12 minutes i.v. with placebo intranasal spray (saline 0.9% + chitosan) with a minimum lock-out interval of 20 minutes for 72 hours or until 40 unit-dose sprays are delivered Patient number We will examine 36 patients, 18 patients in each group. The study duration for an individual patient will be at latest 72 hours, the total study duration is 4 to 5 months. Study importance An intranasal spray is an ideal application form for surgery patients, either in- or outpatients. On the other hand, ketamine and S-ketamine is quite often used in the perioperative setting as a rescue analgesic. In higher doses it could be used as an emergency tool in emergency prehospital medicine. In the perioperative setting it is important to evaluate the efficacy and safety of S-ketamine intranasal spray combined with midazolam intranasal spray in patients. If our study shows that S-ketamine intranasal spray is effective as an analgesic and has good patient acceptance, S-ketamine intranasal spay could be considered as an alternative, completely non-invasive analgesic procedure in a postoperative outpatient setting. As a consequence development of a nasal multidose-applicator combining S-ketamine and midazolam would be of interest.
The purpose of this study is to evaluate the effectiveness and safety of a patient-controlled system to deliver fentanyl compared with a patient-controlled intravenous system to deliver morphine in the management of postoperative pain.
This study was designed to examine the analgesic and side effects of dexmedetomidine-morphine mixture for intravenous patient-controlled analgesia (PCA).
