About this study

Official title: Comparison of the Perioperative Effects of Intra-abdominal Pressure Created With Standard and Valveless Insufflators in Robotic Surgery

The main aim of this study is to compare the perioperative effects of different intra-abdominal pressures and different insufflators in patients undergoing robotic surgery at a 30-45 degree trendelenburg position.

Read the detailed description

Adult patients scheduled for robotic genitourinary or colorectal surgery are going to be enrolled in this study. Patients will be randomized in three groups. In group I, conventional insufflators will be used with 12 mmHg intra-abdominal pressure; in group II, valveless insufflators will be used with 12 mmHg intra-abdominal pressure and in group III, valveless insufflators will be used with 8 mmHg intra-abdominal pressure. Intraoperative data regarding airway pressures, lung compliance, hemodynamic parameters, arterial blood gas analysis, times of pressure loss and camera cleaning will be gathered. Each patient will receive a standardized anesthesia and analgesia procedure with a intravenous morphine patient controlled analgesia (PCA). Postoperative pain will be monitored at 1st, 3rd, 6th, 12th and 24th postoperative hours and morphine consumption rates will be recorded. Patient length of stay, time to first flatus, urine output, postoperative complications(graded by Clavien Dindo classification), preoperative and postoperative hemoglobin and creatinine levels will be filed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Valveless Insufflator with 12 mmHg intra-abdominal pressureDevice

    In this group valveless insufflators, which are relatively new in clinical practice, will be used under low intra-abdominal pressure throughout the surgery.

  • Valveless Insufflator with 8 mmHg intra-abdominal pressureDevice

    In this group valveless insufflators, which are relatively new in clinical practice, will be used under ultra-low intra-abdominal pressure throughout the surgery.

    Measured: Intraoperative and daily untill discharge

  19. Number of participants with pulmonary complications

    Pulmonary complications like atelectasis, pulmonary oedema, pleural effusion, pneumothorax, pneumonia, ventilatory failure will be recorded for each patient. And number of patients with pulmonary complications will be compared among the groups.

    Measured: Postoperative, up to one month

  20. Flatus time

    Postoperative time to first flatus will be recorded

    Measured: Postoperative one week

  21. Time to oral intake

    Postoperative time to oral intake will be recorded

    Measured: Postoperative 3 days

  22. Number of participants with subcutaneous emphysema

    Length of hospital stay will be recorded as hours

    Measured: Postoperative, up to one month

  24. The Clavien-Dindo classification of surgical complications

    Any postoperative complication will be graded by the Clavien-Dindo classification between I to V with I meaning any deviation from the postoperative course without the need for pharmacological treatment or surgical, endoscopic, and radiological interventions and V meaning death of a patient.

    Measured: Postoperative, up to one month

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of manipulations done by the attending anesthesiologists (time frame: Intraoperative). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06132490, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2024.
