Abstract
Aims and Background: Nausea and vomiting after surgery is a common
complication that can cause unpleasant feeling, increased hospitalization time,
and increased cost. Even in some cases it leads to severe dehydration,
electrolyte imbalance, aspiration, pneumonia, and even the opening of the
surgical site which has been sutured. Selecting the device for airway
management may affect postoperative nausea and vomiting, in part due to the
irritation of the airway. Therefore, we decided to compare two methods of
airway management in patients undergoing strabismus surgery regarding the
incidence of postoperative nausea and vomiting.
Materials and Methods: The study population underwent strabismus surgery with
general anesthesia. Patients were randomly divided into two groups with either
endotracheal intubation or laryngeal mask airway insertion. The severity of
nausea and vomiting was assessed in the recovery room, 6, and 18 hours after
the surgery. Nausea was measured according to the Verbal Rating Scale (VRS)
criteria.
Findings: 160 patients were enrolled and divided into two groups
of 80. The groups were identical in terms of demographic data (age, weight,
gender, symptoms, hemodynamics (except for heart rate before induction, 5 min
and 15 min after induction), duration of surgery, number of muscles under
surgery and number of eyes under surgery.
Conclusion: Incidence of PONV in the recovery room, 6 hours and 18
hours after surgery were similar in both groups.

Abstract
Aim and background: Tracheal intubation remains the choice method for keeping airways open during mechanical ventilation. Among the various methods, standard method of direct laryngoscopy generally used by non-skilled staff increases the risk of failure. This study was performed to evaluate and compare the results of tracheal intubation using laryngeal masks vs. glidescope led by novice personnel. Methods and Materials: This descriptive-prospective study were conducted on 31 trainees and interns of Birjand University of Medical Sciences. Each of the participants randomly intubated two patient with laryngeal mask airway or glidescope, and the results were recorded a professional as observer. The maximum authorized turn to try tracheal intubation was once per person with a time limit of 90 seconds. If the participant had two unsuccessful tries or due to a problem regarding the intubation process an anesthesiologist took the control and performed the intubation and the intubation try by the study participant was considered unsuccessful. Findings: Tracheal intubation success rate in laryngoscopic and laryngeal mask airway )LMA( was 90.3% and 96.8%, respectively )P=0.325(. Average time of tracheal intubation in laryngeal mask airway and laryngoscopy group was 29.25 ± 3.90 and 48.25 ± 4.90 )P<0.001(. conclusions: Results of this study suggest a higher rate of success as well as faster intubation for laryngeal mask airway. Due to the cost and feasibility of using this method, the researchers recommend that hospitals should focus on training with and providing laryngeal mask airways

Abstract
Aims and background: Airway management is one of the key skills in managing and treating of critical patients. In hospital departments before reaching an anesthesiologist or experienced team, this task lies with the nurses who have not been trained enough in this field. This study was conducted to evaluate the ability of nurses before and after a manikin-based workshop for securing the airway with laryngeal mask insertion and tracheal intubation. Materials and Methods: In this semi-experimental study, 68 nurses working in a university hospital with record of service of 1 to 12 years were enrolled. First, nurses were evaluated in terms of familiarity with the correct method of oral airway insertion, mask ventilation, laryngeal mask insertion, and intubation with the tracheal tube, using an oral questionnaire. In the next step, their ability to perform the above items on the educational model was evaluated. After completing a total of 10 minutes of theoretical and practical training on a manikin for each nurse, the ability to perform the above tasks with a maximum of two attempts for each task was measured again. Findings: Most nurses said that they were familiar with airway insertion and mask ventilation, but only about 20% of them were able to correctly ventilate the manikin in the pre-test assessment. After a 10-minute training, more than 90% of the participants put the laryngeal mask successfully. The ability for endotracheal intubation was only 13%. conclusion: Adding laryngeal mask to resuscitation trolley and periodic short-term training of nurses might be an effective way to secure the patients’ airway in emergency situations.
