Filter by:Lichtenstein herniorrhaphy still remains one of the most often performed inguinal hernia repair techniques. It is frequently associated with acute postoperative and chronic pain. Due to insufficient effect of non-steroidal anti-inflammatory drugs, they are often overdosed. However opioids have many side effects. Interventional treatment, such as transversus abdominis plain (TAP) block requires an additional intervention and has relatively short effect, also could not be applied in outpatient conditions. The hypoalgesic effect of transcutaneous electric nerve stimulation (TENS) is well known for many years, but effectiveness during postoperative period is still controversial and maybe therefore didn't come to daily practice. However it could be a promising part of multi-modal pain treatment for hernia patients. This study analyse the hypoalgesic effect of TENS and its impact on hernia specific quality of life (QoL) after Lichtenstein hernia repair. Aim#1 To determine whether use of TENS is effective for acute postoperative pain relief. Aim#2 To determine whether use of TENS have impact on hernia specific QoL in early and late postoperative period. Aim#3 To identify factors associated with effectiveness/ineffectiveness of TENS procedures. Aim#4 To determine whether a psychological condition (depression, anxiety and pain catastrophisation) is somehow associated with TENS effectiveness.
The purpose of this study is to compare between two surgical techniques for anterior abdominal wall blocks in obese patients Undergoing Major Gynecological Surgery: Surgical Transversus Abdominis Plane [TAP] block versus Rectus Sheath block as regards the efficacy and adverse effects
studying the effect of dexmeditomidine addition to bupivacaine in bilateral intermediate cervical block for patients undergoing thyroidectomy under general anaesthesia
Laparoscopic cholecystectomy (LC) is a widespread surgical procedure with superior outcomes in terms of the incurred postoperative pain, recovery time, cosmetic, and morbidity issues. Although it is associated with less postoperative pain compared to open cholecystectomy, but patients still experience significant pain. Pain after LC is categorized into three types: referred pain to the right shoulder due to diaphragmatic stretching during gas insufflation; visceral pain due to dissection and injury at the hepatic fossa during gall bladder removal; and somatic pain due to tissue injury at the port sites. Since the discovery of LC in 1987 by a French surgeon, Phillipe Mouret, it became the gold standard for surgical excision of the gallbladder. Local anesthetics (LA) has been tried for analgesia after LC in variable techniques and concentrations. It was proved to be a safe and valid method for reducing pain after LC instilled intraperitoneal and infiltrated at the port sites. Surgicel is an absorbable gelatin sponge that is non-toxic, non-allergenic, non-immunogenic, and non-pyrogenic. It is gamma-sterilized and provided with double packing. The sponge is easily cut to fit the surgical cavity. It may be applied dry to the wound. It absorbs 40 times its weight of whole blood or 50 times of water and adheres easily to the bleeding site. It forms a stable adherent coagulum. When implanted in vivo, it is completely absorbed within 3-5 weeks. The rationale for using this sponge as interposition material is to act as a carrier for the analgesic drugs and allow for its local sustained release, and for local hemostasis. Bupivacaine will be used as the main local anesthetic medication in the study. It provides variable pain relief when either used to irrigate intraperitoneal space as a sole analgesic or combined with opioids. Lidocaine 2% will be mixed with bupivacaine to expedite the onset of analgesia. Epinephrine will be used as 5 microgram/ml of the total mixture of used fluids in order to prolong the time of action of the block.
The purpose of this study is to examine the difference in perioperative pain after shoulder surgery with a standard bupivacaine nerve block compared to liposomal bupivacaine enhanced nerve block alone in TSA and ARCR. Data will be compared using VAS scores and opiate consumption between the two groups. The hypothesis of this study is that an interscalene nerve block with liposomal bupivacaine will decrease both postoperative VAS pain scores and total narcotic consumption when compared to a standard bupivacaine interscalene nerve block alone.
Main purpose of this prospective single center randomized study is to compare the analgesic effect of ultrasound guided Unilateral Oblique Subcostal Transversus Abdominis Plane (TAP),unilateral Erector Spinae Plane (ESP) blocks and Port site infiltration of local anesthetic in subjects undergoing laparoscopic cholecystectomy. Total 100 patients, American society of anaesthesiology physical status I-II aged between 18-65 who underwent laparoscopic cholecystectomy will recruit to the study.
This is a Phase 2, open-label, multi-cohort study to evaluate the analgesic efficacy, safety, and pharmacokinetics (PK) of a single, individualized dose of HTX-011 administered into the surgical site as a monotherapy or with other medications to enhance analgesia in subjects undergoing unilateral simple bunionectomy.
Balanced anesthesia needs optimization of hypnotic, relaxant, and narcotic. Administration of hypnotic drugs can be monitored by bispectral index score (BIS), while the dosage of muscle relaxants can be guided by train-of four (TOF). However, administration of narcotics lacks objective monitor. Overdosage of narcotic may lead to delayed awakening, while underdosage may lead to high degree of postoperative pain. Recently, there is a monitor, Analgesic Nociceptive Index (ANI) monitor, designed to guide the administration of narcotics. There are many descriptive studies supporting the correlation of ANI score and pain score but there are still very few randomized control studies which report the efficacy of ANI in clinical practice.
Patient suffer from moderate posterior knee pain after TKA despite injection of local anesthetic around the femoral or saphenous nerves. Indeed, the posterior part of the knee is innervated by the sciatic nerve. This nerve is not routinely blocked as clinicians fear to produce a motor block of the leg that might impair the postoperative assessment. An analgesic alternative is the infiltration of the knee with local anesthetics performed by the surgeon. Recently a trial(1) demonstrated that a selective tibial nerve block provides an effective analgesia without a motor blockage when compared with a sciatic nerve block. The objective of this randomized controlled double-blinded trial is to assess whether a tibial nerve block is more effective for the postoperative pain than local infiltration analgesia when there are combined with an adductor canal block, without decreasing the functional parameters.
This study evaluates the impact of local anesthetic administration regiment through peri-neural femoral nerve catheter on pain and motor block frequency, after total knee arthroplasty.
