Comparison of laryngeal mask and tracheal tube on duration and complications of anesthesia in reconstructive hand surgery patients

Determining and comparing the duration and complications of anesthesia over time after using a laryngeal mask and tracheal tube in patients undergoing hand reconstruction surgery.

To assign patients to each of the two intervention groups, based on the patient code and random number table, patients are assigned to one of the two tracheal tube or laryngeal mask groups. To calculate the sample size, 45 people are considered in each group. In this study, people will be divided into two groups, laryngeal mask and tracheal tube, by a person knowledgeable about the type of airway control, giving codes to patients and taking into account the entry and exit criteria.

Place of operation: operating room of Ashayer Khorramabad Hospital This study is a single-blind clinical trial. Dividing people into two groups, laryngeal mask and tracheal tube During the surgery, using a checklist, the patient's age, gender, type of surgery, duration of anesthesia and vital signs will be recorded in 4 different times before anesthesia, 10 and 20 minutes after the start of the surgery, in the recovery department of the operating room. became.

Entry requirements: patients undergoing hand repair surgery Patients aged 18-60 years Patients with ASA Ⅰ,Ⅱ Patients' consent to participate in the plan; Conditions of non-entry: presence of congenital diseases of the jaw and face Pregnant patients Abnormal airway anatomy Hemodynamic changes such as increased blood pressure

Laryngeal mask group Tracheal tube group

the amount of sore throat; satisfaction; duration of anesthesia; systolic blood pressure; diastolic blood pressure; oxygen saturation; heart beat; breathing rate; The incidence of cardiac arrhythmias after using a laryngeal mask and tracheal tube varies over time.

Randomization is done through a table of random numbers. That is, the exact number of patients is specified and a code is assigned to each patient. Then, based on the patient code and the table of random numbers, the patients are assigned to one of the two groups of tracheal tube or laryngeal mask by the computer.

This study is a one-blind clinical trial study in such a way that the patient is unaware of the type of respiratory assistance intervention. In other words, the information that can distort the test result remains hidden from the participant's view, but the person responsible for conducting the test is aware of them.
