Active clinical trials for "Hernia, Inguinal"

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.

Inguinal hernia repair (IHR) is one of the most commonly performed operations in general surgery practice. Different pharmacological approaches and interfascial plane blocks are used to control postoperative pain. Erector spinae plane (ESP) block is a relatively new interfascial plane block which was reported to be effective in different types of surgeries. In this study, the primary aim is to assess the effect of ESP on recovery of patients following open IHR surgery.

Multimodal analgesia is used to control postoperative pain in inguinal hernia repair. Transversus abdominis plane block is an effective regional anesthesia technique for postoperative analgesia in inguinal hernia repairs. The erector spinae plane block applied to thelow thoracic region was also reported to provide effective analgesia in these surgeries. In this study, we aimed to determine and compare the effects of transversus abdominis plane block and lumbar erector spinae plane block on postoperative pain in inguinal hernia repairs.

This feasibility study highlights the features of the 3D dynamic responsive prosthesis ProFlor-E® for fixation free obliteration of inguinal hernia defect

Patients were randomized into two groups: Group Gabapentine ( G group) received 600 mg of Gabapentin (two tablets) two hours prior to surgery and saline solution before induction of spinal anesthesia and group Ketamine ( K group) received two placebo tablets and an injection of ketamine at a dosage of 0.15 mg/Kg before induction of spinal anesthesia.. During the surgery, blood pressure and heart rate were monitored. Postoperative analgesia was provided by a PCA morphine. Acute postoperative pain was assessed by a visual analog scale. The incidence of postoperative neuropathic pain was detected by the DN4 questionnaire after one and three months of surgery.

Herniorrhaphy is the most frequent general surgical procedure. There are moderate pain complaints after herniorrhaphy. Besides causing discomfort to the patients, pain, can delay recovery and discharge and cause cognitive dysfunction and difficulty with returning to normal daily activity. A combination of analgesics with different effect sites can reduce the doses needed and analgesic related side effects which is called multimodal analgesia . Opioids, acetaminophen, nonsteroid anti-inflammatory drugs and cox-2 inhibitors, alfa-2 receptor agonists, steroids, gabapentin and pregabalin have been used for this purpose(4). Tizanidine is an alfa-2 receptor agonist, and is used for musculoskeletal pain conditions. Tizanidine reduced the local anesthetic requirement in spinal anesthesia. The aim of this study is to investigate the hypothesis that: Tizanidine can reduce the pain scores, analgesic consumption, analgesic related side effects and provide early return to normal daily activity compared to placebo after inguinal herniorrhaphy.

The purpose of this study is to determine whether early (before NICU discharge) or late (55-60 weeks post-menstrual age) inguinal hernia repair is safer for premature infants who have an inguinal hernia.

This an open, uncontrolled multicenter clinical study to assess the safety and performance of the WK-6 surgical mesh in adult patients with unilateral inguinal hernia. The primary objective is to determine the safety of the WK-6 surgical mesh. Data will be compared retrospectively with published studies on inguinal hernia mesh. The secondary objectives are to explore the performance of the surgical mesh by measuring the pain pre and post surgery as well as a number of relevant variables for establishing the performance of the mesh. Data will be compared retrospectively with previous studies on inguinal hernia mesh with a follow-up of at least one year.

The purpose of the study is to evaluate mid and long term postoperative pain and further disabling complications in open inguinal hernia repair by Lichtenstein technique after mesh fixation with fibrin sealant (FS), compared to mesh fixation with sutures.

Increasingly in general surgery, the investigators are conducting outpatient day surgery. Ambulatory surgery currently comprises 60 to 70% of surgeries performed in North America. These patients all require some form of analgesia which can be taken at home in the first few days after the surgery. The current standard at the investigators' centre and many others in the maritime provinces is to provide a prescription for oral acetaminophen plus codeine or oxycodone (Tylenol #3®, Percocet ®). Some patients may receive more potent opioids such as oral hydromorphone (Dilaudid®). Unfortunately, the most commonly prescribed medication (Tylenol #3®) is often poorly tolerated by patients, has several undesirable side effects, and may not provide effective pain relief. In the investigators' experience, non-steroidal anti-inflammatory drugs (NSAIDs) are uncommonly a routine addition to the home analgesic regimen. Tylenol #3®, in the investigators' experience and opinion, is a poor post surgical pain medication. They hope to show that a combination of ibuprofen and acetaminophen is better for pain relief after these procedures. The combination of acetaminophen and ibuprofen would be a safe, cheap, and readily available regimen. Unfortunately, as the prescribing practices of surgeons are old habits, it will require a very convincing argument to get them to change their practices. A randomized controlled trial comparing these two regimens, the investigators hope, would be a powerful enough argument. The hypothesis of this study, therefore, is that the pain control provided by a combination of acetaminophen plus ibuprofen (650 mg/400 mg four times per day) will be superior to Tylenol #3® (600 mg acetaminophen/60 mg codeine/15 mg caffeine four times per day). This study will attempt to enroll 150 patients in total. Eligible patients will be identified by their attending surgeon and contacted by study personnel. Patients who enroll in the study will undergo their surgery in the usual manner. After the surgery, in the recovery room, once they are ready to go home, they will be randomized to receive combination A or B and be given a week's worth of pain medication. They will then go home and take this medication as directed. They will record their pain intensity and pain relief once per day using a diary provided in the study package. One week after their surgery, they will return to the hospital clinic and be seen by the study nurse. They will hand over the diary and any unused medication. They will also be asked several questions regarding their overall satisfaction, incidence of side effects, and how long until they were pain free. The risks of participating in this study are minimal from the risks inherent to the procedures and medications the patients would receive within the standard of care. Ibuprofen is a commonly used NSAID which is widely available over the counter and has an established safety profile. The most common adverse effects of ibuprofen and other NSAIDs are gastrointestinal bleeding and ulceration. Other less common adverse effects include nephrotoxicity, hypersensitivity reactions, hepatic dysfunction (longterm use), and cognitive dysfunction. The investigators' patients will be selected to exclude those most at risk for these complications (see exclusion criteria). Acetaminophen has few side effects, with no adverse effects on platelet function and no evidence of gastric irritation.
