Modified thoracoabdominal nerves block through perichondrial approach: a new strategy with a wide range of utilization in laparoscopic gynecological surgeries

Background Modified thoracoabdominal nerve block via the perichondrial approach (M-TAPA) was expressed lately as an effective regional anesthetic technique involving the anterolateral aspects of the thoracoabdominal wall via deposition of local anesthetics to the perichondrium’s underneath side. Even though the efficacy of M-TAPA has been registered, additional research is advocated. The rationale of the current study was to evaluate the analgesic effectiveness of M-TAPA blockade accomplished before surgery in subjects undergoing laparoscopic gynecological surgeries. Patients and methods 60 female patients (20–65 years) were categorized randomly into two groups. Group (M): received bilateral M-TAPA using bupivacaine (0.25%), whereas group (C): (control group) received conventional general anesthesia with multimodal analgesia. Postoperative pain assessment, time to first rescue analgesic requirement, total opioid consumption during the first 24 h postoperatively, and patients’ satisfaction were recorded. Also, the time to modify the Aldrete score greater than or equal to 9 was estimated. Results Pain scores were significantly lower in the M-TAPA group versus the control group at all times of measurement ( P <0.05 at each time point). Also, the total amount of opioid consumption was significantly less in the M-TAPA group versus the control group. Patients in the M-TAPA group were statistically more satisfied with their analgesia ( P <0.001) and attained a modified Aldrete score greater than or equal to 9 earlier than those in the control group. Conclusions Ultrasound-guided M-TAPA block achieved efficient analgesia to the anterolateral aspects of the anterior abdominal wall and reduced opioid consumption in patients who underwent laparoscopic gynecological surgeries.
