Evaluation of the Effectiveness of Modified Pectoral Nerve Blocks Type II (PECS II) for Vascular Access Port Implantation Using Cephalic Vein Venesection

Abstract

The vascular access port implantation procedure can be performed using the venesection method by inserting a catheter into the cephalic vein in the region of the deltopectoral groove. This method eliminates the need for catheter tunneling. An alternative method to infiltration anaesthesia for port implantation may be a modified pectoral nerve block type II (PECS II). This study aimed to evaluate the effectiveness of modified PECS II for vascular access port implantation using cephalic vein venesection. This retrospective observational study was conducted at the 4th Military Clinical Hospital in Wroclaw, Poland. A group of 114 patients underwent the modified PECS II block and additional cutaneous infiltration anesthesia at the incision line. Pain intensity was assessed on the NRS scale measured intraoperatively at four points. The QoR-15 questionnaire was used to assess patient satisfaction during the first 24 h after surgery. The operator’s condition assessment score was used to assess surgical conditions and operator comfort. The analysis showed that the median pain intensity during vascular port implantation was 0. A statistically significant difference in pain intensity was demonstrated between the specialist’s group and the resident’s group at the second and third measurement points (p < 0.008; p < 0.012). The mean value on the QoR-15 scale was 132. There was a significant difference between the pain scores of the groups. The mean score in the pain position in the specialist’s group was 18 points and in the resident’s group, it was 19 points (p < 0.029). In conclusion, the present study revealed that the modified PECS II block is an effective and safe method of anesthesia for Port-A-Cath implantation.
