CMRA for US-guided-MWA of Liver Tumors

Combined Multiple Regional Anesthesia for Microwave Ablation of Liver Tumors

• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 122 (estimated)
• Sponsor: Lu Wang · Academic / Other
• Sex: All
• Age: 18 Years – 80 Years
• Healthy volunteers: Not accepted

Summary

Patients with liver tumors who underwent US-guided-MWA of liver tumors were enrolled. These patients were allocated into three groups based on tumor size and number: A, B, and C. Prior to the ablation procedure, Group A patients received a combination of hepatic hilar block (HHB), Transversus abdominis plane block (TAPB), and local anesthesia (LA). Patients in Group B were administered HHB in conjunction with LA, while those in Group C received TAPB and LA. Evaluative parameters included the Numerical Rating Scale (NRS) scores, consumption of morphine, incidence of complications, and factors influencing perioperative pain.

Detailed description

Patients with liver tumors who underwent US-guided-MWA of liver tumors were enrolled. These patients were allocated into three groups based on tumor size and number: A, B, and C. Prior to the ablation procedure, Group A patients received a combination of hepatic hilar block (HHB), Transversus abdominis plane block (TAPB), and local anesthesia (LA). Patients in Group B were administered HHB in conjunction with LA, while those in Group C received TAPB and LA.Pain levels were routinely assessed through the Numerical Rating Scale (NRS), with scores being recorded by the attending nurse every 15 minutes. The frequency of these assessments would be increased if the patient reported discomfort or if there were changes observed in vital signs. If a patient reported a pain level of ≥4 on the NRS scale, an intravenous dose of 10mg morphine was administered, provided that cardiopulmonary safety could be assured. The determination of cardiopulmonary safety was made by the interventional radiologist (M. L. with 20 years of experience). Following the ablation procedure, all patients were monitored for a period of 36 hours. During this period, several parameters were recorded at the time of the procedure and again at 4, 8-, 12-, 24-, and 36-hours post-procedure. These parameters included the NRS score, vital signs, any need for morphine, and the occurrence of any adverse events.
