Comparison of three supraglottic devices in anesthetised paralyzed children undergoing elective surgery.

ABSTRACT: The newest variation of the i-gel supraglottic airway is a pediatric version.This study was designed to investigate the usefulness of the size 2 i-gel compared with the ProSeal laryngeal mask airway (PLMA) and classic laryngeal mask airway (cLMA) of the same size in anesthetized, paralyzed children.A prospective, randomized, single-blinded study was conducted in a tertiary care teaching hospital.Ninety ASA grade I-II patients undergoing lower abdominal, inguinal and orthopedic surgery were included in this prospective study. The patients were randomly assigned to the i-gel, PLMA and cLMA groups (30 patients in each group). Size 2 supraglottic airway was inserted according to the assigned group. We assessed ease of insertion, hemodynamic data, oropharyngeal sealing pressure and postoperative complications.There were no differences in the demographic and hemodynamic data among the three groups. The airway leak pressure of the i-gel group (27.1±2.6 cmH(2)O) was significantly higher than that of the PLMA group (22.73±1.2 cmH(2)O) and the cLMA group (23.63±2.3 cmH(2)O). The success rates for first attempt of insertion were similar among the three devices. There were no differences in the incidence of postoperative airway trauma, sore throat or hoarse cry in the three groups.Hemodynamic parameters, ease of insertion and postoperative complications were comparable among the i-gel, PLMA and cLMA groups, but airway sealing pressure was significantly higher in the i-gel group.

Project description:Objective Hemodynamic changes occur in almost one-third of patients undergoing spinal anesthesia, which are likely to effect vital organ. The aim of this study is to determine the hemodynamic effect of spinal anesthesia during different phases of menstrual cycle. Methods This is a descriptive cross-sectional study, two hundred and seventy-three patients who underwent spinal anesthesia for elective surgery were enrolled in this study. Of all the patients, 141 patients were in the luteal phase and 132 patients were in the follicular phase of their menstrual cycle. Analytical epidemiological study was conducted using questionnaires. Blood pressure and heart rate of patients before, immediately after, and 1 h after spinal anesthesia were recorded, and the data were analyzed using SPSS software. Results In the follicular phase before anesthesia, systolic blood pressure (SBP) was 127.5 ± 3.9, diastolic blood pressure (DBP) was 80.3 ± 6.2 mmHg and heart rate (HR) was 82.0 ± 8.5bpm, while, immediately after the induction of anesthesia following recordings were measured; 109.7 ± 9.13, 71.8 ± 2.8 mmHg and 70.0 ± 8.10bpm, respectively. In the luteal phase, it was 126.9 ± 3.12, 81.6 ± 9.3 mmHg and 80.2 ± 4.4bpm, and 122.0 ± 9.12, 78.6 ± 8.5 mmHg and 75.9 ± 6.5bpm respectively before and immediately after anesthesia, these changes in the menstrual phase was significant (P < 0.001). In the follicular phase an hour after spinal anesthesia, the mean SBP was 100.3 ± 3.9, DBP was 71.2 ± 7.5, MAP was 87.0 ± 4.7 mmHg and HR 67.5 ± 5.7bpm and following was seen in luteal phase; 115.4 ± 1.8, 75.9 ± 2.3, 97.3 ± 3.5 mm Hg and 74.0 ± 7.4bpm, respectively. These values were significantly lower in the follicular phase (P < 0.001). Conclusion Spinal anesthesia in the luteal phase as compared to the follicular phase of the menstrual cycle shows less variation in hemodynamic parameters. Highlights • Hemodynamic changes occur in almost one-third of patients undergoing spinal anesthesia.• Spinal anesthesia in the luteal phase as compared to the follicular phase of the menstrual cycle.• Our study did not measure the levels of progesterone and estrogen.• Comparative studies including women with circulatory abnormalities, preoperative and postoperative analysis.
