Comparison of Efficacy of Bupivacaine Alone vs. Bupivacaine-Tramadol in Lower Limb Surgery

This randomized controlled trial aims to compare the effectiveness of bupivacaine alone versus bupivacaine combined with tramadol for postoperative analgesia in patients undergoing lower limb surgeries under spinal anesthesia. A total of 60 patients, aged 18-70 years and classified as ASA I or II, were included and randomly divided into two groups of 30 patients each. The bupivacaine group received 15 mg of 0.75% hyperbaric bupivacaine, while the combination group received 15 mg bupivacaine with 15 mg tramadol. Postoperative pain was assessed using the Visual Analogue Scale (VAS), and the duration of analgesia was recorded as the time from administration of the drug until the patient developed a VAS score of ≥3, indicating the need for rescue analgesia. The findings suggested that adding tramadol to bupivacaine provided better and longer-lasting postoperative pain relief compared with bupivacaine alone.

Low Versus Standard Volume EXORA Block in Laparoscopic Cholecystectomy

The original EXORA block used high local anesthetic volume (50 mL total), raising concerns about local anesthetic systemic toxicity (LAST). In such a bilaterally administered regional technique, evaluating the efficacy of a reduced-volume approach is warranted to maximize patient safety.

Oral Acetaminophen for Post-Op Pain Management in Bariatric Surgery Patients

Adult patients with morbid obesity who have had Roux-en-Y gastric bypass (RYGB) or laparoscopic sleeve gastrectomy (LSG) surgery have impaired drug metabolism. There is a paucity of information available on how these patients metabolize acetaminophen post operatively and if drug preparation has any effect on achieving adequate pain control. The surgery may alter the stomach pH, reduce surface area of the stomach, affect transit time, and alter anatomic and physiologic standard absorption of medications. Due to these anatomic and physiologic changes, we seek to understand the potential effects of liquid versus pill formulations of acetaminophen on pain control in this patient population. The purpose of this study is to assess for subjective and objective measures of optimized pain control between formulations of acetaminophen including oral pills and oral liquid.

Postoperative Tizanidine Use in Pelvic Reconstructive Surgery: A Pilot Study

The goal of this clinical trial is to evaluate whether adding tizanidine to the standard postoperative pain regimen improves recovery after pelvic reconstructive surgery in adult women. The main questions it aims to answer are: Does postoperative tizanidine improve patient-reported recovery 4-6 weeks after surgery? Does tizanidine reduce postoperative pain, opioid use, constipation, and healthcare utilization while improving functional recovery? Researchers will compare standard postoperative care plus tizanidine with standard postoperative care alone to determine whether tizanidine improves postoperative recovery. Participants will: * Be randomly assigned to receive either standard postoperative pain management alone or standard postoperative pain management plus tizanidine for 2 weeks after surgery. * Complete electronic surveys before surgery, 1-2 days after surgery, 2 weeks after surgery, and 4-6 weeks after surgery to assess pain, recovery, activity, and bowel function. * Allow researchers to review information from their electronic medical record, including healthcare utilization and postoperative outcomes, during the 4-6 weeks following surgery.

The Impact of Perioperative Lidocaine Infusions on Enhanced Recovery After Non-Cardiac Surgery

The goal of this single-center, pragmatic, randomized, blinded, placebo-controlled trial is to evaluate the impact of intravenous (IV) lidocaine within the existing Enhanced Recovery After Surgery (ERAS)program on outcomes in patients after major non-cardiac surgery. The main questions the trial aims to answer are: The primary hypothesis is that utilization of IV lidocaine as part of a perioperative multimodal pain regimen will result in a reduction in hospital Case Mix Index-Adjusted Resource Length of Stay (CARLOS). The secondary hypotheses are that lidocaine infusion will result in a reduction in total inpatient opioid consumption (oral morphine milligram equivalents, oMMEs) and pain scores, and improved surgical outcomes (including return of bowel function, ileus, nausea, rapid responses called, surgical site infections, and ICU transfers), while also having minimal incidence of side effects (including double/blurry vision, tinnitus, sedation, and adverse events requiring early cessation).

Photobiomodulation Therapy for Pain Control in Post-Operative Total Knee Arthroplasty Patients: A Pilot Study

A pilot study to assess the efficacy and feasibility of PBMT for pain control in patients undergoing a TKA and are discharged the same day from an ambulatory surgery center.

Analgesic Efficacy of Combined PECS II and PIP Block Versus Thoracic Paravertebral Block Post-Mastectomy

Postoperative pain management is crucial for patients undergoing mastectomy for breast cancer. Regional analgesia techniques, such as the Thoracic Paravertebral Block (TPVB), are commonly used to reduce pain and opioid consumption; however, TPVB carries potential risks, including pneumothorax. Interfascial plane blocks, specifically the Pectoral Nerve II (PECS II) block combined with the Superficial Parasternal Intercostal Plane (PIP) block, have emerged as alternative techniques to provide comprehensive analgesia to both the lateral and anterior chest wall. The purpose of this randomized controlled trial is to evaluate and compare the analgesic efficacy and quality of postoperative recovery between a combination of ultrasound-guided PECS II and PIP blocks versus the standard Thoracic Paravertebral Block (TPVB) in patients undergoing mastectomy with or without axillary lymph node dissection (ALND). Participants will be randomly assigned to receive either the combined PECS II and PIP block or the TPVB following general anesthesia induction. Pain scores, total opioid consumption, time to first analgesic request, quality of recovery using the QoR-15 questionnaire, and potential block-related complications will be monitored and compared over the 24-hour postoperative period.

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

Prevention of Rebound Pain After Orthopaedic Surgery With Peripheral Nerve Block (REBOUND)_part B

Rebound pain after peripheral nerve blocks reduces the benefits of regional anesthesia and increases opioid consumption. This rebound pain most likely results from suboptimal pain management, as patients receiving a peripheral nerve block are typically not given scheduled opioid doses. Oral Patient Controlled Analgesia (PCA) consists of an oral morphine prescription that allows patients to self-administer doses based on their pain score. This study will compare patients undergoing elective orthopaedic surgery under general anaesthesia or sedation with a peripheral nerve block, receiving oral morphine PCA either with or without additional scheduled oral morphine doses.

This rebound pain most likely results from suboptimal pain management, as patients receiving a peripheral nerve block are typically not given scheduled opioid doses. Oral Patient Controlled Analgesia (PCA) consists of an oral morphine prescription that allows patients to self-administer doses based on their pain score. This study will compare patients undergoing elective orthopaedic surgery under general anaesthesia or sedation with a peripheral nerve block, receiving oral morphine PCA either with or without additional scheduled oral morphine doses.

Weight-Adjusted Diclofenac Potassium Medicated Lollipop for Post-Adenotonsillectomy Pain in Children

\*\*Brief Summary\*\* This study aimed to develop and conduct a preliminary clinical evaluation of a novel weight-adjusted gelatin-based diclofenac potassium medicated lollipop for the management of postoperative pain following adenotonsillectomy in children. The formulation was designed to improve analgesic adherence by providing a palatable and child-friendly dosage form suitable for oral transmucosal administration. Fifty paediatric patients aged 4 to 12 years undergoing elective adenotonsillectomy received one of three weight-adjusted diclofenac potassium lollipop doses (15 mg, 20 mg, or 30 mg) every 8 hours during the first 24 postoperative hours. The study assessed postoperative pain intensity, product acceptability, rescue analgesic use, and safety. In parallel, the formulation underwent pharmaceutical characterization, including physicochemical and microbiological quality evaluation.

Comparative Study Between Ultrasound Guided Paravertebral Plane Block and Erector Spinae Plane Block on Post-operative Analgesia After Total Abdominal Hysterectomy

The intent of this study is to compare the efficacy of the erector spinae plane block (ESPB) and paravertebral plane block in reducing postoperative opioid consumption and pain in patients with total abdominal hysterectomy.

The Effect of Lactoferrin on Pain Management Following Cesarean Section

This study evaluates whether lactoferrin, a naturally occurring protein with anti-inflammatory and antioxidant properties, can improve pain control after cesarean section. Effective management of postoperative pain is essential to support maternal recovery, mobility, and the ability to care for the newborn, while minimizing reliance on opioid medications and their associated side effects. In this randomized, double-blind, placebo-controlled trial, women undergoing elective cesarean section will receive either oral lactoferrin or a matching placebo in addition to standard postoperative analgesia. Lactoferrin will be administered starting before surgery and continued for 48 hours after delivery. The study will assess whether lactoferrin reduces postoperative pain intensity and opioid consumption, and improves recovery outcomes such as time to mobilization, patient satisfaction, and incidence of common postoperative symptoms. Safety and tolerability will also be evaluated.

Erector Spinae Plane Versus Quadratus Lumborum Blocks for Pain Management After Total Abdominal Hysterectomy

TAH, being a large scale gynaecological operation, is a construction bound to cause serious postoperative pain to the patient in that the procedure will inevitably entail massive tissue dissection. Management of this postoperative pain is of utmost significance because poor analgesia may lead to delayed mobilization of the patient, long duration of hospitalization and also general increase in the morbidity of postoperative period. Traditionally, in these facilities, opioid analgesics are the most common and the most popular means of controlling postoperative pain. Nevertheless, the varied and pervasive use of opioids is largely constrained by its well-reported, dose-dependent systemic adverse effects. Nausea, vomiting, sedation, and respiratory depression are complications that severely degrade the recovery process of the patient and reduce his or her satisfaction.

Preoperative High-Dose Oral Paracetamol for Postoperative Analgesia in Children Undergoing Tonsillectomy"

This randomized clinical trial compares two different preoperative doses of oral paracetamol (acetaminophen) in children undergoing elective tonsillectomy. The aim is to determine whether a higher loading dose (30 mg/kg) decreases the need for opioid rescue medication after surgery compared with the standard dose (15 mg/kg), when used as part of a multimodal pain management approach. Children aged 3 to 15 years will be randomly assigned to receive either 30 mg/kg or 15 mg/kg of oral paracetamol before surgery. All participants will receive the same standard anesthesia and postoperative pain management. The primary outcome is the total amount of rescue opioid (fentanyl) required during the first 12 hours after surgery. Secondary outcomes include postoperative pain scores and the occurrence of side effects such as nausea and vomiting. This study seeks to determine whether a higher initial dose of paracetamol offers additional clinical benefits in pediatric tonsillectomy with multimodal analgesia.

Peripheral Autonomic Block (BAP) Plus Transversus Abdominis Plane Block (TAP) for Postoperative Analgesia After Minimally Invasive Left-Sided Colorectal Resection (BAPTAP)

Effective postoperative pain management is essential for enhanced recovery after laparoscopic colorectal surgery. This randomized, controlled, double-blind trial will compare conventional postoperative analgesia (intravenous medications plus surgical wound infiltration) with a locoregional strategy combining a peripheral autonomic block (inferior mesenteric and superior hypogastric plexuses) and a transversus abdominis plane (TAP) block. We hypothesize that the combined strategy (BAPTAP) reduces pain intensity and opioid consumption in the first 48 hours after Left-Sided Colorectal Resection.

Comparison of Supra vs Infra Inguinal Fascia Iliaca Blocks for Spinal Positioning and Analgesia in Lower Limb Surgery

Severe pain associated with thigh and knee fractures makes the positioning for regional anesthesia a challenge. Different modalities to make patient pain free for spinal positioning, post op analgesia and patient satisfaction including supra-inguinal fascia iliaca block (S-FIB) and infra-inguinal fascia iliaca blocks (I-FIB) have been studies. The aim of this study is to compare two blocks in patients undergoing thigh and knee surgeries. A randomized controlled trial study design will be used and 60 patients fulfilling the inclusion criteria will be included. The patients will be divided into 2 groups by simple random sampling. Group A (S-FIB) (n = 30, those who will receive 30 ml of 0.125% bupivacaine) and Group B (I-FIB) (n = 30, those who will receive 30 ml of 0.125% bupivacaine). Depending on the allotted group, patients will be given the block under the guidance of ultrasound in the preoperative area. After block patients will be assessed for ease of spinal positioning using EOSP Scale, postoperative duration of analgesia and patient satisfaction using Likert Scale and data will be recorded on prescribed proforma. All the findings will be noted in a specially designed proforma by the researcher. All the data collected will be entered and analyzed. Quantitative variables will be presented with mean ± SD. Independent sample t-test for duration of postoperative analgesia. Qualitative variables such as ease of spinal positioning and gender will be presented with Chi-Square. A p-value equal to or less than 0.05 will be considered significant.

Transnasal Sphenopalatine Ganglion Block for Postoperative Pain and Recovery in Tonsillectomy (TONwoPA)

The aim of this clinical trial is to evaluate the effectiveness of transnasal transmucosal sphenopalatine ganglion block in reducing post-tonsillectomy pain. The study also investigates its impact on rescue analgesic requirements and postoperative recovery by comparing 5% lidocaine with placebo. Participants will receive a transnasal transmucosal sphenopalatine ganglion block with either 5% lidocaine or placebo (saline). Postoperative pain levels and opioid consumption will be monitored during the first 24 hours after surgery. In addition, length of hospital stay, the occurrence of primary and secondary post-tonsillectomy hemorrhage up to 14 days, unplanned hospital readmissions after discharge, and patient satisfaction on postoperative day 14 will be assessed.

Supplementary Nerve Blocks Added to the Adductor Canal Block for Postoperative Pain Management in Primary Total Knee Arthroplasty: A Randomized Controlled Comparison of Sciatic, BiFeS, and IPACK Techniques

Postoperative pain following total knee arthroplasty (TKA) is a significant clinical problem that delays early mobilization, reduces patient satisfaction, and increases analgesic requirements. The adductor canal block (ACB), which aims to provide analgesia while preserving motor function, is widely used in postoperative pain management after TKA. However, clinical and anatomical studies have demonstrated that ACB is effective only in the anteromedial sensory innervation of the knee and does not adequately block pain originating from the posterior knee capsule. This limitation reduces analgesic effectiveness, particularly in patients with a prominent posterior pain component. The sciatic nerve block has long been considered the gold standard for managing posterior knee pain. However, due to disadvantages such as motor weakness and delayed rehabilitation, current pain management protocols increasingly favor motor-sparing and complementary approaches such as the Biceps Femoris Short Head (BiFeS) block and the Interspace Between the Popliteal Artery and the Capsule of the posterior Knee (IPACK) block for posterior knee analgesia. In light of this information, the aim of our study is to guide clinical practice by comparing the postoperative analgesic efficacy, motor function outcomes, and patient satisfaction associated with sciatic nerve, BiFeS, and IPACK block techniques-each administered as a supplement to the adductor canal block-in patients undergoing total knee arthroplasty, with the ultimate goal of determining the optimal block combination for postoperative pain control.

Comparative Analysis Of Dexmedetomidine And Dexamethasone As An Adjuvant To 0.5%Ropivacaine On Onset Of Ultrasound Guided Supraclavicular Brachial Plexus Block In Patients Undergoing Upper Limb Surgeries

To compare the efficacy of dexmedetomidine and dexamethasone as an adjuvant to 0.5%ropivacaine on onset of ultrasound guided supraclavicular brachial plexus block in patients undergoing upper limb surgeries. Ropivacaine hydrochloride, a long acting local anesthetic, is commonly used for supraclavicular block owing to its favorable safety profile especially in terms of minimal cardiotoxicity and less motor block. Dexmedetomidine, a highly selective alpha-2 adrenergic agonist, enhances the quality of supraclavicular block by providing sedation and analgesia while potentially prolonging the duration of block through hyperpolarization of nerve fibers. While, Dexamethasone, a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties, prolongs duration of analgesia by reducing perineural inflammation and inhibiting nociceptive signal transmission. Supraclavicular brachial plexus block offers dense anesthesia for surgical procedures at or distal to the elbow with relatively high success rate, once described as "spinal of the arm". Moreover, supraclavicular brachial plexus block is an excellent alternative to general anesthesia in upper limb surgeries.

Comparison of Pericapsular Nerve Group (PENG) Block With a Combined Femoral, Sciatic, Lateral Femoral Cutaneous Nerve Block for Postoperative Analgesia in Secondary Total Hip Arthroplasty; (REVPET)

The aim of this clinical trial is to compare the analgesic effect of a pericapsular nerve group (PENG) block with a combined femoral, sciatic, lateral femoral cutaneous nerve block for postoperative analgesia in patients scheduled for secondary total hip arthroplasty. The primary objective of this study is to compare postoperative pain management between the PENG block and the combined block (femoral, sciatic, lateral femoral cutaneous) by measuring postoperative morphine consumption in each of the two groups. Participants will be randomized into two groups. Patients assigned to the PENG group will receive a PENG block with ropivacaine, followed by a sham (sciatic) block, and spinal anesthesia with isobaric bupivacaine. Patients assigned to the combined block group will receive femoral, sciatic, lateral femoral cutaneous nerve blocks with ropivacaine, followed by spinal anesthesia with isobaric bupivacaine.

Dexamethasone in Prolonging the Duration of Spinal Anesthesia Among Pregnant Patients

Lower segment C section is one of the most commonly performed surgeries worldwide. It is performed in spinal anesthesia. During Spinal Anesthesia a local anesthetic drug is administered in a space surrounding spinal cord and it blocks nerves originating from spinal cord providing both anesthesia and analgesia. This technique avoids harmful exposure of drugs to the baby inside the womb of mother. However this technique provides anesthesia and analgesia of limited duration which can be prolonged by addition of drugs to patient management regimen. One such drug is Dexamethasone which is a steroid commonly administered in the peri-operative period.

Intravenous Ibuprofen Postoperative Analgesia After Abdominal Hysterectomy

The current research is designed to investigate the analgesic efficacy of intravenous ibuprofen on the postoperative analgesic requirements, pain intensity and other recovery parameters.

Dexmedetomidine and Bupivacaine Intra-articular for Postoperative Analgesia After Knee Arthroscopic Surgery

The aim of this study to compare the analgesic effects of intraarticular dexmedetomidine added to bupivacaine with those of bupivacaine alone after knee arthroscopy
