Trial summary

One of most common bariatric surgery is laparoscopic sleeve gastrectomy. Pain after laparoscopic surgery may be due to stretching of the intra-abdominal cavity, peritoneal inflammation, and diaphragmatic irritation caused by residual carbon-dioxide in the peritoneal cavity.Multimodal efforts like parenteral opioids… Read more about this study

About this study

Official title: Intraperitoneal Versus Intravenous Dexmedetomidine for Post-operative Analgesia Following Laparoscopic Sleeve Gastrectomy Surgery, A Prospective Randomized Control Trial.

One of most common bariatric surgery is laparoscopic sleeve gastrectomy. Pain after laparoscopic surgery may be due to stretching of the intra-abdominal cavity, peritoneal inflammation, and diaphragmatic irritation caused by residual carbon-dioxide in the peritoneal cavity.Multimodal efforts like parenteral opioids, non-steroidal anti-inflammatory drugs or local wound infiltration have been done to reduce overall pain and benefit post-operative conditions of patients undergoing laparoscopic surgeries. Despite their efficacy, with all parenteral medications, there are associated adverse effects.

Intraperitoneal local anesthetic is a safe and effective analgesic approach which used to control pain after laparoscopic surgery. Many authors have evaluated the role of IP local anesthetic administration in laparoscopic colorectal cancer surgery, laparoscopic cholecystectomy, laparoscopic appendectomy and laparoscopic hysterectomy

Read the detailed description

Laparoscopic procedures have many advantages over open procedures such as lesser haemorrhage, better cosmetic results, lesser post-operative pain, and shorter recovery time, leading to shorter hospital stay and less expenditure.One of most common bariatric surgery is laparoscopic sleeve gastrectomy. Pain after laparoscopic surgery may be due to stretching of the intra-abdominal cavity, peritoneal inflammation, and diaphragmatic irritation caused by residual carbon-dioxide in the peritoneal cavity.

Multimodal efforts like parenteral opioids, non-steroidal anti-inflammatory drugs or local wound infiltration have been done to reduce overall pain and benefit post-operative conditions of patients undergoing laparoscopic surgeries. Despite their efficacy, with all parenteral medications, there are associated adverse effects.

Intraperitoneal local anesthetic is a safe and effective analgesic approach which used to control pain after laparoscopic surgery. Many authors have evaluated the role of IP local anesthetic administration in laparoscopic colorectal cancer surgery, laparoscopic cholecystectomy, laparoscopic appendectomy and laparoscopic hysterectomy.

Dexmedetomidine (alpha-2 adrenergic agonists) has become one of the frequently used drugs in anesthesia as it has been reported to provide analgesia, anxiolysis, and an anesthetic-sparing action with minimal respiratory depression plus its sedative effect that mimics natural sleep. Dexmedetomidine can used safely both intravenous and plus bupivacaine in different nerve block.

What participants receive

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

  • intraperitoneal local anaesthetic instillationProcedure or surgery

    intraperitoneal anesthetic instillation (40 ml total volume containing bupivacaine 0.25) through the trocar at the subdiaphragmatic space in Trendelenburg's position for 5 min with intravenous infusion of 50 ml normal saline over 10 minutes.

Questions about this trial

What is this clinical trial studying?

A study testing intraperitoneal local anaesthetic instillation in people with Postoperative Pain After Laparoscopic Sleeve Gastrectomy, run by Tanta University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. 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?

Time of first analgesic request (time frame: postoperative first day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Dec 2020.
