Transverse Abdominis Plane (TAP) Block Versus Transversalis Fascia Plane Block (TFPB) After Cesarean Delivery

Outcomes of Postoperative Analgesia Protocols and Their Impact on Recovery Quality in Patients Undergoing Cesarean Section

Postoperative analgesia treatment methods are applied to the living in the operating room. It is a routine part of the process of these applications. It is necessary from medical and ethical perspectives. Postoperative analgesia applications are started in the preoperative period and continue in the postoperative period. The analgesic treatment to be used is shaped according to the application and experience of the anesthesiologist. The scientifically accepted developed method is multimodal analgesia protocols. These protocols cover a wide range from paracetamol to opioids, peripheral and central blocks (such as Transversalis Fascial Plane Block (TFPB) and Transversus Abdominis Plane (TAP) Block). The aim of this study is to continue the analgesia protocols applied in cesarean section surgeries on the first 24-hour pain scores, the amount of opioid consumed after surgery and the quality of obstetric recovery (ObsQoR-10) scale.

Detailed Description

Postoperative analgesia treatment methods are applied to the living in the operating room. It is a routine part of the process of these applications. It is necessary from medical and ethical perspectives. Postoperative analgesia applications are started in the preoperative period and continue in the postoperative period. The analgesic treatment to be used is shaped according to the application and experience of the anesthesiologist. The scientifically accepted developed method is multimodal analgesia protocols. These protocols cover a wide range from paracetamol to opioids, peripheral and central blocks (such as Transversalis Fascial Plane Block (TFPB) and Transversus Abdominis Plane (TAP) Block). In this study, transversus abdominis plane block or transversalis fascial plane block was applied to the participants immediately after surgery. The aim is to continue the analgesia protocols applied to the cesarean section surgeries on the pain scores in the first 24 hours, the amount of opioid consumed after surgery and the quality of obstetric recovery (ObsQoR-10) scale.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Group 1; Transversus abdominis plane block was performed immediately after cesarean section.	Other: Transversus abdominis plane (TAP) block; We apply different nerve blocks to patients for pain relief after cesarean surgery. Transversus abdominis plane block was applied to this group
Group 2; Transversalis fascial plane block was performed immediately after cesarean section	Other: Transversalis Fascia Plane Block; We apply different nerve blocks to patients for pain relief after cesarean surgery. Transversalis Fascia Plane Block was applied to this group

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Postoperative pain	Pain levels of patients will be evaluated with the Numerical Pain Scale (NRS) in the first 24 hours postoperatively. The numeric rating scale (NRS) is a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-10 scale, with zero meaning "no pain" and 10 meaning "the worst pain imaginable"	postoperative 24 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
ObsQoR-10	The ObsQoR-10 questionnaire consists of 10 questions that assess the patient-reported quality of recovery in obstetric patients' postoperative period using an 11-point Likert scale (0 = strongly negative; 10 = strongly positive) that points to a minimum score of 0 (worst possible recovery) and a maximum score of 100 (best possible recovery)	Postoperative 24 hours
