Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The anesthesiologist administered the intervention. After induction and insertion of classic LMA/ProSeal LMA/ i-gel, volume controlled ventilation mode was set and we recorded the respiratory dynamics, heartbeat, systolic, diastolic, mean arterial pressures every 5 minutes during surgery. Surgery usually 60 minutes. We also recorded complications like sore throat, nausea and vomiting after surgery. Allocation is determined by computer randomized technique. The fidelity to the intervention is assessed by the audit of operation notes and anesthesia machine records.

The LMA is designed to sit in the patient’s hypopharynx and cover the supraglottic structures, thereby allowing relative isolation of the trachea.
LMA ProSeal has a built-in drain tube that allows expelled gastric content to bypass the pharynx. This specific feature is designed to decrease the risk of aspiration. The i-gel is the second generation supraglottic airway device, it works in harmony with the patient's anatomy so that compression and displacement trauma are significantly reduced

Outcomes
Primary outcome [1] 319498 0
ease of insertion
Timepoint [1] 319498 0
We tried to insert the airway device three times, if we insert it for the first time, we call it an easy insertion, if we insert it at the second or third time, we call it difficult
Primary outcome [2] 319909 0
time of airway devices insertion
Timepoint [2] 319909 0
We record the time of insertion from the time laryngeal mask airway passes the incisor teeth until we see end-tidal CO2.
Secondary outcome [1] 368486 0
complications like sore throat, nause and vomiting
There is no test or tools we simply asked patients about sore throat, and we observed them about nause and vomiting in the recovery room for half an hour
Timepoint [1] 368486 0
after surgery for half an hour
