Active clinical trials for "Pain, Postoperative"

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.

In this study the investigators wish to compare the effect of a selective axillary nerve block to placebo in patients undergoing arthroscopic shoulder surgery. It is the investigators hypothesis that the amount of morphine consumption in the first 4 hours postoperatively in the intervention group will be significant lower than in the placebo group.

The objective of the study is to evaluate the efficacy and safety of a single oral dose of naproxen sodium 440 mg in combination with DPH (diphenhydramine) 25 mg in subjects with postsurgical dental pain and phase advanced sleep.

Local anesthetics (LA) are increasingly used for postoperative pain management. Speicifically, several studies have found benefit of LA injected intra-abdominally following abdominal hysterectomy. However, it remains unclear whether the pain relief seen is due to local anesthetic mechanisms within the abdominal cavity or through systemic absorption. The aim of this study is to assess whether lidocaine administered intravenously has similar analgesic efficacy as the same dose administered intra-abdominally in patients undergoing abdominal hysterectomy. All patients would have rescue analgesia using the patient controlled analgesia (PCA) pump with morphine in order to achieve adequate pain management during 24 h.

The study was performed in urology patients elicited for open prostatectomy or open nephrectomy. Comparison of analgesic effect between group (M) with spinal morphine before general anaesthesia and group without this intervention was measured.

Analgesia in liver surgery is a challenge, postoperative coagulopathy risk raises fears an epidural haematoma formation following the epidural analgesia, "gold standard" in major abdominal surgery. The spinal analgesia and/or continuous wound infiltration of local anesthetics constitute so an alternative. The study will compare the continuous infiltration of local anesthetics and rachianalgesia in terms of decreased postoperative morphine consumption and incidences of chronic postoperative pain at 3 and 6 months after hepatic surgery compared to the control group.

A Phase 2, Randomized, Controlled, Multicenter, Evaluation of the Efficacy and Safety of Locally Administered HTX-011 for Postoperative Analgesia Following Bunionectomy

Adductor canal block (ACB) is a new technique gaining acceptance as an alternative analgesic method of femoral nerve block (FNB) following knee surgery. The advantage of ACB is its dominant sensory nerve block effect. It preserves quadriceps muscle strength compared with the FNB. This will serve as potential gain for early rehabilitation and thereby functional outcome. Adequate direct injection of local anesthetic into the canal will block four nerves: the saphenous nerve, the nerve to the vastus medialis, the medial femoral cutaneous nerve, and the terminal end of the posterior division of the obturator nerve. Anterior cruciate ligament reconstruction (ACLR) is often associated with postoperative severe pain. Postoperative early rehabilitation is the primary focus to restore pre-injury status and is an essential part of the full recovery, especially that this rehabilitation extents over a 6 month period. Early elimination of pain is necessary to achieve this goal. However, there are no clear conclusive clinical reports defining the adequate analgesic volume-dosage of local anesthetic for ACB for postoperative ACL pain management. The investigators speculated that volume-dosage manipulation play key role in the effective of ACB for postoperative pain. The investigators conducted this prospective, randomized, observer-blinded trial to compare 3 combinations of volume and dosage of 0.25 % bupivacaine for US-guided ACB. The first aim of the investigation is to compare the analgesic effect of ACB 0.25% bupivacaine of the 3 doses as assessed by the visual analog scale (VAS) pain scores. The second aim were duration of analgesia, as defined by first demand for analgesia, and subsequent 24-h consumption. Physiotherapy tolerance and time to discharge were evaluated. Side effects were also assessed.

The hypothesis of the study is whether dexmedetomidine plus local anesthetic ropivacaine could extend the pain relieve time compared with only ropivacaine when thoracic paravertebral block is performed at the end of video-assisted pneumonectomy.

In many countries, caesarean section (CS) rates have been increasing. The international literature is unclear regarding the analgesic efficacy of the transversus abdominis plane block (TAPB) after a CS. In particular, no clinical trials exist in which the correct method of performing this block has been matched with the obtained analgesic effect after a CS. The primary goal of the study was to determine whether a correctly performed ultrasound-guided TAPB (USG-TAPB) could provide patients who underwent a CS with better control of acute postoperative pain during the first 72 hours after surgery
