Recovery and immune function after low pressure pneumoperitoneum during robot-assisted radical prostatectomy: a...

Area of Science:

• Anesthesiology
• Surgical Oncology
• Intraoperative Management

Background:

• Robot-assisted radical prostatectomy (RARP) involves specific intraoperative challenges.
• Optimizing intra-abdominal pressure (IAP) and neuromuscular block (NMB) is crucial for patient outcomes.
• Assessing the impact of deep NMB with low IAP on recovery and immune function is important.

Purpose of the Study:

• To compare low IAP with deep NMB against standard practice in RARP.
• To evaluate effects on quality of recovery, immune function, and parietal perfusion.
• To determine if deep NMB and low IAP enhance patient recovery post-RARP.

Main Methods:

• Blinded, randomized controlled trial with 96 patients undergoing RARP.
• Experimental group: low IAP (8 mmHg) with deep NMB (post-tetanic count 1-2).
• Control group: standard IAP (14 mmHg) with moderate NMB (train-of-four 1-2).
• Assessed recovery via questionnaires, immune function via biomarkers, and perfusion via indocyanine green.

Main Results:

• Quality of recovery was not superior in the low IAP/deep NMB group.
• Clinical outcomes (pain, nausea, vomiting, hospital stay) were similar between groups.
• No significant differences in immune function markers were observed.
• Low IAP facilitated by deep NMB demonstrated improved parietal peritoneum perfusion.

Conclusions:

• Low IAP with deep NMB did not improve quality of recovery or preserve immune function in RARP patients.
• Parietal peritoneum perfusion was enhanced, but this did not translate to better overall recovery.
• Standard practice remains comparable for recovery and immune function in RARP.
