Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Time of LMA insertion. Timepoint: Once. Method of measurement: The time from mouth opening to proof chest expantion with compresion of anesthesia bag. | — |
Secondary
| Measure | Time frame |
|---|---|
| Ease of LMA insertion. Timepoint: once. Method of measurement: Straightforward = completion of insertion in first attempt in less than 15 second, and without displacement. Slightly difficult = completion of insertion in first attempt in more than 15 second, and with displacement. Difficult = completion of insertion needs more than one attempt, in more than 30 second ,and with multiple displacements .;Patients' response to LMA insertion. Timepoint: Once , for two minute in the beginning of anesthesia , and after insertion of LMA and insufflation of that cuffs. Method of measurement: Yes = movement of limbs, coughing, straining,resistance against manually ventilation , and keeping breathing. No = absence of the aforementioned conditions.;Air leak from the LMA environment. Timepoint: Once. Method of measurement: Yes= Audible sound in the time of mandatory ventilation . NO= Loss of sound in the time of mandatory ventilation.;The number of attempts to insertion of LMA. Timepoint: Once. Method of measurement: The number of times that the LMA imported from the outside the mouth to verify its accuracy of insertion , and the number will be written.;The quality of pulmonary ventilation. Timepoint: Once. Method of measurement: Good = good chest expansion, lack of audible air leaks, lack of gastric distention, and square wave in Capnography.Bad = lack of previous conditions.;Recovery time. Timepoint: Once. Method of measurement: The time between discontinuation of drugs to elevating of head for 10 minutes.;Cardiovascular profile. Timepoint: before injection of anesthetic drugs , after injection of anesthetic drugs , after insertion of LMA , every 15 minutes tell recovery from anesthesia. Method of measurement: By automated monitor ( sadat co. Iran).;Complications during removal of LMA. Timepoint: After removal of LMA, until exit of patient from post-anesthesia care unit. Method of measurement: with the patient monitoring. | — |
