Active clinical trials for "Pain, Postoperative"

The investigators aim is to study the effect of pre-operative local anesthetic on post vaginal hysterectomy pain.

Both Ultrasound guided Adductor Canal Block ( ACB) and Femoral Nerve Block (FNB) has been used to provide postoperative analgesia for knee surgeries. To the investigators' knowledge, no comparison has been made between those blocks in relation to postoperative quadriceps muscle strength, or duration and quality of postoperative analgesia for arthroscopic ACL reconstruction in pediatrics. If ACB provides postoperative analgesia after arthroscopic knee surgery comparable to FNB, it has the potential to improve the postoperative outcome as it will lead to less quadriceps muscle weakness and early mobilization, both of which are very important in the early postoperative period.

This project will evaluate the integration of lavender essential oil in surgical patients during the perioperative and postoperative phase of care. The study will assess patients' pain, sleep quality, and mood. The goal is to support that lavender oil will decrease pain scores and narcotic use, increase sleep quality, and decrease anxiety by improving overall patient satisfaction and supporting their natural sense of well being. This research project will help support the use of complementary medicine in a hospital setting. The increased awareness and use of complementary medicine in a hospital setting will strengthen the patient centered care model that all hospitals strive to achieve.

Interscalene brachial plexus block constitutes the analgesic criterion standard for shoulder surgery. However it is associated with a high incidence of hemidiaphragmatic paralysis (HDP) that may not be tolerated by patients with chronic pulmonary disease. This randomized controlled trial will compare ultrasound-guided interscalene block (ISB) and supraclavicular block in patients undergoing arthroscopic shoulder surgery. The main outcome is static pain at 30 minutes after arrival in the post anesthesia care unit (PACU) as measured by a numerical rate scale (NRS) from 0 to 10. Our research hypothesis is that interscalene and supraclavicular blocks will result in equivalent postoperative analgesia at 30 minutes in the PACU. The equivalence margin is set at 2 points

Transversus abdominis plane (TAP) block provides effective analgesia and is now a standard of care for analgesia after cesarean section. There is no information on levobupivacaine pharmacokinetics post TAP after pregnancy. Objective: Generate a pharmacokinetic levobupivacaine model and its effect on the electrocardiogram (ECG). Method: The investigators will study 12 healthy term pregnant patients, scheduled for elective cesarean section under spinal anesthesia. A bilateral TAP block is performed with 20 ml 0.25% levobupivacaine with epinephrine 5 ug/ml. Sensory block will be assessed at 1-2-6 and 12 hours post puncture. 2 ml of venous blood will be obtained at 2-5-10-30-45-60-90 and 180 minutes. With a Holter machine we will study the effect of levobupivacaine plasma levels and the QTc changes. Expected results: 1) Plasma levobupivacaine levels; 2) Changes in QTc .

Objectives: To examine the efficacy and safety of electroacupuncture (EA) combined with auricular acupuncture (AA) in reducing post-operative pain in patients following abdominal surgery for gynecological diseases. Hypothesis: Acupuncture is effective and safe to reduce postoperative pain during the first 5 days following surgery as compared to a sham control. Design and strategy: This is a randomized, placebo-controlled, subject- and assessor-blind trial. Seventy-two subjects will be recruited and randomized (in 1:1 ratio) to receive either acupuncture treatment or sham control. Subjects in both groups will undergo standard operation procedure and receive post-operative analgesics based on usual care. Study instrument: A 10-point pain Numerical Rating Scale (NRS) will be employed as a primary outcome assessment. Intervention: Subjects in the treatment group will receive EA combined with AA within two hours before operation, post-operation upon arrival to the ward and once a day for the subsequent 5 days. Subjects in the control group will receive non-invasive sham procedure in the same schedule. Main outcome measures: Primary outcome: NRS pain scores will be measured upon recovery, hourly at 6 hours after surgery, then 4-hourly until day 2, 6-hourly until day 3 and once daily until discharge. Secondary outcome: Morphine consumption, post-operative syndromes, quality of recovery questionnaire, SF-6D, EQ-5D-5L and adverse events will be documented and compared between groups. Data analysis: Pain intensity during the first 5 days will be calculated by Area Under the Curve (AUC) of NRS pain scores. AUC between the two groups will be compared by Student's T-test. Expected outcome: AUC of the acupuncture group is expected to be significantly lower than sham acupuncture group.

In this study, it was aimed to investigating and comparing the postoperative effects of leukocyte- and platelet-rich fibrin (L-PRF) and advanced platelet-rich fibrin (A-PRF) in terms of pain, swelling on the cheek, and trismus after mandibular third molar surgery. The study included a total of 27 patients with bilateral impacted mandibular third molar which surgically operated at different times. Patients were evaluated in two randomly separated groups. For the first group; A-PRF and for the second group; L-PRF was applied into the tooth socket. The outcomes variables were; pain, swelling, the number of analgesics taken, and trismus. These variables were also assessed on the basis of; 1st, 2nd, 3rd and 7th days following the operation.

Laparoscopic prostatectomy (LP) is characterized by substantial tissue trauma, despite its minimally -invasive approach. Although postoperative pain intensity is lower when compared to open procedures, the use of opioids is common. Retrospective review of available LP cases revealed that although analgesic demand varied, nearly all of our LP patients required opioids postoperatively. Bilateral Quadratus Lumborum Block (QLB), being one of relatively new features of regional anesthesia, offers good analgesia of abdominal wall, with the potential for control of visceral pain. This study was established to evaluate its effectiveness in alleviating pain after radical prostatectomy in a double - blind, placebo - controlled manner.

Local intra-articular injection of anesthetics (LIA) is increasingly used during knee arthroscopy for pain relief. The LIA can only be performed at the end of surgery as the knee joint is continuously flushed during the arthroscopy. As a consequence, an optimal analgesic effect is only obtained one hour after surgery and opiates are typically used as pain relief in the immediate postoperative period. Since these opiates have a number of side effects such as nausea, vomiting and drowsiness, other analgetic methods are desirable. Intravenous administration of lidocaine, a safe, inexpensive analgesic, is already used in major (abdominal) surgeries and might also be a promising method for pain relief in the first hour after knee arthroscopy, in anticipation of the onset of the analgesic effect of the LIA. The aim of this study is to verify if systemic administration of lidocaine has a beneficial effect on the pain immediately after knee arthroscopy. In addition, the effect of systemic lidocaine administration on postoperative nausea, vomiting and general patient comfort will be evaluated.

The purpose of this study is to evaluate how effective is the intraoperative use of lidocaine to attenuate postoperative pain and opioids consumption after laparoscopic cholecystectomy
