Filter by:The postoperative period following cesarean is associated with moderate to severe pain that requires a considerable amount of analgesics that carry with them side-effects such as nausea, vomiting, fatigue and immobilization. Several studies have tried, with variable results, to find a more effective analgesia alternative such as infusion of local anesthetics through a catheter in the surgical wound sinus, a practice that has currently been widely used in clinical practice. Despite existing references on its use in the postoperative period following cesareans there continues to be a lack of information on other aspects. The investigators study hypothesis is that the use of levobupivacaine in the surgical wound will reduce the surface of hyperalgesia compared to the control group.
This study will help to answer the question, "Does injecting local anesthetic before laparoscopic instrument ports are placed decrease pain after surgery?" Patients participating will be randomly assigned to receive local anesthetic or saline injection at the site of a laparoscopic instrument port as part of their planned surgery. After surgery at 4 and 24 hours the patient will be asked to rate their pain on a simple chart.
The study carry out is to determine whether the use of oral pregabalin premedication to assess the analgesic efficacy, opiod sparing, adverse effect and clinical value in post-operative pain management.
The purpose of the study is to prove that pain scores generated from painful stimuli applied preoperatively may help identify the inter-individual variability in pain perception.
This study is a single-center, randomized, placebo-controlled, double-blind clinical trial. The purpose of this study is to evaluate the impact of pre-operative transverses abdominis plane (TAP) blocks on post-operative analgesia in patients undergoing robotic surgery for gynecologic cancers.
The previous studies have shown that recovery after laparoscopic or vaginal hysterectomy is faster than after abdominal approach. The aim of this study is to evaluate postoperative pain after vaginal or laparoscopic hysterectomy. The primary outcome measurement is opioid consumption.
The investigators hypothesize that patient controlled analgesia (PCA) provides superior pain relief and patient satisfaction when compared to scheduled intravenous analgesia following vaginal reconstructive surgery.
The aim of the present study is to evaluate the analgesic benefit of intravenous lidocaine and ketamine in the perioperative period of abdominal surgery.
Cerebral palsy is common. It affects approximately 3 per 1000 children. Hip displacement due to muscle tightness (spasticity) occurs in up to half of the more severely affected children, and many of these children require major (bony) hip surgery. After bony hip surgery the management of pain is very difficult, as spasticity tends to increase and causes painful spasms which are difficult to control. Botulinum Toxin injections are known to reduce spasticity and therefore should also reduce pain. These injections take at least a week to work, but the effects can last for months. Botulinum Toxin is already an established treatment for chronic hip pain prior to surgery. The investigators aim to find out whether Botulinum Toxin injections can reduce post-operative pain. The identification of the level of pain can be challenging because most of these children are unable to communicate verbally. The investigators are therefore using a validated pain scoring tool that was designed especially for such children. This study will be the first to describe fully the pain experience of children with cerebral palsy undergoing this type of major surgery. The investigators will compare Botulinum Toxin injections with placebo (non-active) injections. There is a high emotional and financial burden on the families of these children. Families describe high levels of emotional distress around the time of surgery, particularly when their child is in pain. Difficulty with pain control post operatively may delay discharge from hospital and parental return to work. It causes disrupted sleep for the child and family and may delay the child's return to school. The results of this study will be shared with professionals and families at international conferences and in scientific and popular (patient-based) publications. This study cannot be undertaken in adults with cerebral palsy as they only rarely undergo this sort of surgery.
The impact of anaesthetic method (intravenous vs. inhalational) has been proposed, but not proven in a large-scale study. The researchers aim to provide an investigation that has sufficient power to clarify the potential effect of anaesthetic method on postoperative need of opioids. Sevoflurane and propofol will be compared.
