Comparison of Post Operative Analgesia in Patients Undergoing Lower Abdominal Surgeries Receiving Ultrasound Guided Block With Dexmetomidine vs Dexmethasone

Lower abdominal surgeries cause significant pain and can be managed by injecting local anesthetic agents between muscles of abdominal wall that can provide post operative pain relief and its duration can be prolonged by adding drugs to local anesthetic regimen

Visually Guided TAP Block in Laparoscopic TAPP Hernia Repair

This prospective, randomized clinical study aims to evaluate the effectiveness of the Transversus Abdominis Plane (TAP) block performed under direct laparoscopic vision in reducing postoperative pain and improving recovery after laparoscopic inguinal hernia repair using the TAPP (Transabdominal Preperitoneal) technique. The study will enroll 100 adult patients undergoing elective laparoscopic TAPP hernia repair at the University Clinical Hospital in Olsztyn, Poland. Participants will be randomly assigned to two equal groups. In the study group, a bilateral TAP block will be performed under direct vision using 20 ml of 0.25% bupivacaine on each side after establishing pneumoperitoneum. The control group will undergo the same surgical procedure without the TAP block. All patients will receive standardized anesthesia and postoperative pain management according to hospital protocol. Postoperative pain intensity will be assessed using the Visual Analogue Scale (VAS) at 0, 6, and 12 hours after surgery. Additional data, such as time to mobilization, use of rescue analgesics, and occurrence of postoperative complications (hematoma, swelling, subcutaneous emphysema, transient muscle weakness), will also be recorded. The primary goal of this study is to determine whether a laparoscopically guided TAP block can effectively reduce postoperative pain and improve recovery parameters following TAPP hernia repair. The results may help establish a simple, safe, and reproducible method of multimodal analgesia in minimally invasive inguinal hernia surgery.

M-Tapa Block and Transversus Abdominal Plane Block for Postoperative Analgesia in Unilateral Open Inguinal Hernia Repair Surgery

Patients will be called to the operating room one hour before surgery and no premedication will be applied before coming to the operating room. Patients in both groups who are taken to the block room will be administered 1-2 mg iv midazolam for sedation. M TAPA block will be applied for the surgical procedure. After aseptic conditions are provided, the high-frequency linear US probe will be covered with a sterile sheath. The US probe will be placed in the saggital plane at the costochondral angle where the midclavicular line intersects the costal cartilage. 5 ml of saline will be injected using the in-plane technique using a 22G 100 mm block needle and the block location will be verified. After the block location is verified, a total of 20 ml of 0.25% bupivacaine will be injected unilaterally and the procedure will be terminated. After aseptic conditions are provided, the high-frequency linear US probe will be covered with a sterile sheath. In TAP block, the block needle will be advanced to the fascial plane between the internal oblique and transversus abdominis muscles with the in-plane technique and the procedure will be completed by injecting 5 ml 20 ml 0.25% bupivacaine unilaterally. The same analgesia protocol will be applied to both groups intraoperatively and postoperatively, and a survey will be conducted on the patients at the 24th hour postoperatively.

Laparoscopic-Assisted Transversus Abdominus Plane Block Versus Intraperitoneal Irrigation of Local Anesthetic for Patients Undergoing Laparoscopic Cholecystectomy

This study is being performed to investigate whether the administration of local anaesthetic into the muscles in the abdomen or onto squirting the local anaesthetic onto the liver following keyhole gallbladder surgery is more beneficial in reducing pain post-operatively. Keyhole gallbladder surgery is typically performed under general anaesthesia (or while the patient is 'fully asleep'), however doctors use other pain relief types to reduce pain after the operation. One of these options is local anaesthetic, which involves the injection of an medication into or onto the part of the body which has been operated on. The reason for doing this is to reduce the pain felt by the patient in the part if the body where the operation occurred. The best way of using these medications remain unclear. The local anaesthetic being used in the study is fully approved for use in Ireland and the drug itself is not being tested. In other words, the drug is not an experimental drug. Local anaesthetic drugs are given in different ways in patients who have just had the keyhole surgery on their gall bladder (this is the surgery that you are about to have). Therefore, the aim of this study is to compare two ways of giving patients these local anaesthetic medications following key-hole gallbladder surgery. These include (1) injecting the medication into the skin at the surgical wounds and squirting it onto the liver (where the gallbladder has been removed from), or (2) injecting the medication into the skin at the surgical wounds and into the muscles in the abdomen (known formally as a transversus abdominus plane block).

Preoperative TAP Block Versus Postoperative TAP Block in Patients Undergoing Laparoscopic Cholecystectomy: a Randomized Controlled Trial

The goal of this clinical trial is to learn if the regional anesthesia technique "TAP block" provide more analgesia when performed before or after the surgery. The main questions it aims to answer are: Does preoperative TAP block provide greater analgesia than postoperative TAP block? Patients receiving preoperative TAP block will have less pain and take less painkillers than patients receiving postoperative TAP block? Participants will: Receive preoperative or postoperative TAP block They will be asked about their pain levels during the hospital stay.
