Assessment of the Efficacy of Transversus Abdominis Plane Block in Alleviating Acute Appendicitis Pain in the Emergency Department
Assessment of the Efficacy of Transversus Abdominis Plane Block in Alleviating Acute Appendicitis Pain in the Emergency Department
This study aims to evaluate the efficacy of Transversus Abdominis Plane (TAP) block in preoperative pain management for patients diagnosed with acute appendicitis who are scheduled for emergency surgery in the emergency department. The research seeks to assess the potential of TAP block in reducing pain intensity prior to surgical intervention among patients diagnosed with acute appendicitis in the emergency setting. The goal is to contribute insights that can enhance practical approaches to achieving optimal pain control for acute appendicitis patients in emergency department settings.
This study will include patients who present to the emergency department with abdominal pain, receive a diagnosis of acute appendicitis through history, physical examination, and imaging modalities, and are determined to undergo definitive surgery following general surgical consultation. Participants will be systematically allocated to three groups. Systemic allocation will be achieved by allocating the first 3 patients to the T-50 group, the second 3 patients to the TAP-50 group, and the third 3 patients to the TAP-100 group. Following treatment, patients' Numeric Rating Scale (NRS) scores will be recorded at 30, 60, and 120 minutes during rest, coughing, and heel tap. If the NRS score is above 5, rescue analgesia will be administered as a 50 mcg fentanyl intravenous infusion over 15 minutes. Subsequently, patient demographic data including age, gender, height, weight, BMI, comorbidities, and medications, as well as vital signs upon admission, complete blood count values, coagulation parameters, creatine kinase levels, appendicitis rupture/non-rupture status, planned laparoscopic/open surgery, Alvarado score, time to first rescue analgesia after baseline analgesia administration (minutes), total analgesic requirement in the emergency department (mg), and TAP block complications (hematoma, surgical site infection, intra-abdominal collection, intramuscular injection - myonecrosis) will be documented. Patient satisfaction will be assessed using a 5-point Likert scale. cutaneous sensory distribution will be assessed at 20 minutes following TAP block. Following this, operative duration (minutes), time to first rescue analgesia postoperatively (minutes), postoperative 2, 4, 6, 12, 24-hour nausea-vomiting (PONV) score, NRS scores during rest, coughing, and heel tap at postoperative 2, 4, 6, 12, 24 hours, cumulative analgesic medications at postoperative 2, 4, 6, 12, 24 hours, postoperative rescue antiemetic requirement, total analgesic cost, and length of hospital stay (days) will be recorded.
