Low Gas Pressure vs Standard Gas Pressure in Robotic Surgery
Comparison Between Low Pressure (8 mmHg) AirSeal Insufflation vs Standard Pressure (15 mmHg) Pneumoperitoneum on Postoperative Recovery in Minimally Invasive Robotic Surgery: A Randomized Controlled Trial
During surgery that is done using a robot, the surgeon needs to put carbon dioxide gas into the belly to lift the belly wall. This is done so the surgeon can adequately see all the body organs and operate safely. Many surgeons currently use a standard pressure of 15 mmHg (a unit to measure pressure). However, many patients find the use of this pressure to be painful after surgery. New research has shown that using a lower pressure with a device called "AirSeal" can safely reduce pain and lead to faster recovery after surgery.
The goal of this clinical trial is to learn if using a lower gas pressure with the AirSeal device during robotic surgery, compared to standard gas pressure with conventional devices, helps adults feel less pain and recover faster.
The study includes adults aged 18 or older having robotic at New York-Presbyterian Hospital/Weill Cornell Medical Center.
The main questions this clinical trial aims to answer are:
- Does using lower gas pressure shorten the time people spend in the recovery room after surgery?
- Does using lower gas pressure lead to less pain and reduce the need for pain medicine after surgery?

Részletes leírás
Robotic surgeries require the use of pneumoperitoneum, which is a standard of care as it creates a working environment to utilize minimally invasive tools to accomplish surgical procedures. However, there is no uniform standard pressure (usually between 12-15 mmHg). Moreover, maintaining the same pressure throughout the procedure can be inconsistent at best. Elevations in pneumoperitoneum cause significant stretch to the peritoneum which results in significant postoperative pain, longer post-anesthesia care unit (PACU) stay times, and higher opioid consumption. These effects are amplified to a higher degree in patients with severe obesity. If the pressures can be maintained and set to lower levels, then patients may have the opportunity to recover in the immediate postoperative period.
The AirSeal Robotic Solution (CONMED Corporation) is an FDA 510(k)-cleared carbon dioxide insufflation device that is indicated for use in robotic-assisted surgery.
This study is a prospective, single-center, single-blind, double-arm parallel-group randomized controlled trial that aims to determine if the use of low-pressure (8 mmHg) AirSeal insufflation, compared to standard-pressure (15 mmHg) pneumoperitoneum, provides superior patient outcomes in terms of post-operative recovery time and convalescence.
During the preoperative evaluation, participants will be consented and enrolled into the trial. Participants will then be randomly allocated to either low-pressure AirSeal insufflation (8 mmHg) or standard-pressure pneumoperitoneum (15 mmHg). Patients and outcome assessors will be blinded to allocation; however, for safety purposes, the operating surgeon and anesthesiologist cannot be blinded.
Intraoperative data (including operation time, estimated blood loss, abdominal pressure, and pressure deviations) will be recorded. Participant data related to comorbidities (i.e. body mass index, American Society of Anesthesiologists physical status, hypertension, diabetes, obstructive sleep apnea, chronic obstructive pulmonary disease/asthma, and smoking status) will be collected from the electronic medical record.

Kísérleti: Low-pressure pneumoperitoneum (AirSeal)
Participants who are assigned to this arm will receive 8 mmHg pneumoperitoneum using the AirSeal Robotic Solution device. The AirSeal Robotic Solution device is a FDA 510(k)-cleared carbon dioxide insufflation platform with valveless trocar technology that helps to maintain stable intra-abdominal pressure during surgery. |
The experimental intervention is low-pressure pneumoperitoneum at 8 mmHg using the AirSeal Robotic Solution device. The AirSeal Robotic Solution (CONMED Corporation) is an FDA 510(k)-cleared carbon dioxide insufflation device that is indicated for use in robotic-assisted surgery. It consists of a console, tri-lumen filtered tube set, and access ports that function as valveless trocars. The console of the device is mounted on a cart and regulates carbon dioxide flow and smoke evacuation by continuously measuring the intra-abdominal pressure. The trilumen filtered tube set carries carbon dioxide to the abdomen, transmits pressure information back to the console, and returns gas from the abdomen for smoke evacuation and filtration. These features allow for the device to operate in the "AirSeal" mode, whereby the pressure within the abdomen is effectively kept constant. The valveless trocars are access ports for the minimally invasive tools to enter the abdominal cavity. |

The control intervention is standard-pressure pneumoperitoneum set at a pressure of 15 mmHg.
This will be delivered using the operating room's conventional valved-trocar carbon dioxide insufflator.

Average post-anesthesia care unit (PACU) length of stay in minutes from PACU admission to PACU discharge order
Időkeret: From PACU arrival (5 minutes post-surgery) to PACU discharge-order (1 to 4 hours post-surgery)
|
The PACU is the area where participants recover from anesthesia after surgery. The PACU recovery time will be computed in minutes as the interval between the documented PACU arrival timestamp and the documented PACU discharge-order timestamp which will both be abstracted from the institutional electronic medical record. The discharge-order timestamp represents the clinical decision that the participant is fit to leave the PACU and is therefore not confounded by factors such as transport delays. |
