Anesthesiological and surgical perspectives on using 8 mmHg versus 12 mmHg pneumoperitoneum pressures during robotic radical prostatectomy: Results of a prospective randomized study.

BACKGROUND: This study aims to compare the effects of 8 mmHg and 12 mmHg pneumoperitoneum (PNP) pressures on operative, postoperative, and anesthesiological parameters in robot-assisted laparoscopic radical prostatectomy (RARP). METHODS: In this prospective study, 43 patients undergoing RARP performed by a single experienced surgeon were randomly assigned to either the low-pressure group (8 mmHg - Group I) or the standard-pressure group (12 mmHg - Group II). We evaluated the operative and postoperative parameters from both urological and anesthesiological perspectives. All patients were treated using the AirSeal® insufflation system. RESULTS: No statistically significant differences were observed between the groups in terms of console time, estimated blood loss, time to first flatus, or hospital length of stay. PNP was increased due to bleeding in six patients in the 8 mmHg group and two patients in the 12 mmHg group. Except for the heart rate measured five minutes after the initial incision, there were no observed differences between the groups in terms of blood pressure, ventilation, and administered medications. The heart rate was significantly lower in Group I (54.4 vs. 68.8, p=0.006). Additionally, during the surgery, the number of manipulations performed by the anesthesiologists, including drug administrations and ventilator management, was significantly lower in Group I (6.1 vs. 9.6, p=0.041). CONCLUSION: In RARP, while the 8 mmHg PNP pressure does not demonstrate differences in operative parameters compared to the 12 mmHg pressure, it offers the advantage of requiring fewer anesthetic interventions, thus minimizing the impact on cardiovascular and respiratory systems.

Selective Dorsal Scapular Nerve and Long Thoracic Nerve Blocks for Rescue Analgesia in Scapulothoracic Arthrodesis Surgery: A Case Report.

Scapulothoracic arthrodesis (STA) surgery is performed to stabilize the scapula in patients with facioscapulohumeral dystrophy (FSHD). Postoperative pain could be a major problem even while using erector spinae plane block (ESPB). We performed a preoperative ESPB with an intraoperative ESPB catheter, but rescue analgesia was needed for pain in the periscapular area in the postoperative period. The patient's pain score was reduced by applying an ultrasound-guided dorsal scapular nerve (DSN) and long thoracic nerve (LTN) block. Selective DSN and LTN blocks can be effective in enhancing postoperative analgesia in STA surgery.

Multiple Thoracic Wall Blocks for Awake Breast Surgery: A Case Report.

Awake breast surgeries under nerve blocks have been a challenge for anaesthesiologists, and different block combinations have been used for surgery under sedation. Thoracic paravertebral block (TPVB) was thought to be sufficient alone for surgical anaesthesia of the breast. We performed a combination of TPVB, pectoralis nerve I block, and serratus anterior plane block for awake breast surgery in an elderly patient with serious comorbidities. Surgical anaesthesia was achieved, excluding skin incision. Any regional anaesthesia technique alone is not sufficient; rather, multiple thoracic wall blocks are needed for surgical anaesthesia of the breast.
