Effect of Preoperative Anxiety on Depth of Anaesthesia and In Vitro Fertilization Success.

Objective: Infertility anxiety may have a harmful effect on embryo quality and fertilization during in vitro fertilization (IVF). Monitoring brain function gives real-time information about the depth of anaesthesia of a patient. This study examined the effect of preoperative anxiety on the depth of anaesthesia and IVF success. Methods: One hundred thirty-one patients who had undergone oocyte retrieval were divided into two groups according to the Beck Anxiety Inventory (BAI): the low-anxious Group L (n = 71) and high-anxious Group H (n = 60). Hemodynamic stability, intraoperative total propofol and fentanyl consumption, good quality embryo (GQE) rate, and fertilization rate were recorded. Results: Fertilization and GQE rates were not significant between groups L and H. Total propofol consumption was significantly higher in group H than in group L. Heart rate (HR) preoperatively and postoperatively and systolic arterial pressure (SAP) preoperatively and diastolic arterial pressure (DAP) postoperatively were significantly increased in group H than in group L. The time for the modified Aldrete score to reach 9 (MAS 9) in group H was significantly higher than that in group L. The effect of variables that were found significantly in the univariate analysis (Propofol, HRpreop, HRpostop, SAPpreop, DAPpostop, and MAS 9) on BAI score. Conclusion: Total propofol consumption was higher in patients with high anxiety levels, but it did not have a negative effect on IVF success.

The Effect of Cerebral Oxygen Saturation Changes on Early Postoperative Neuropsychological Function in Patients Undergoing Cranial Surgery.

AIM: To compare the incidence of postoperative neuropsychological dysfunction in patients managed with cerebral saturation monitoring versus traditional approaches. MATERIAL AND METHODS: A hundred patients undergoing elective intracranial surgery were divided into two groups to receive intraoperative management via cerebral saturation monitoring (Group O) or the conventional approach (Group C). The postoperative neuropsychological function was evaluated by the antisaccadic eye movement test (ASEM) and the Mini-Mental State Examination (MMSE). These tests were performed preoperatively and postoperatively on the first, second, and fifth days. The time for the modified Aldrete score to reach 9 (MAS 9), adverse effects, and pain using a Visual Analog Scale (VAS) scores were recorded. RESULTS: Patient characteristics and surgery data were not statistically different. The MAS 9 of group O was significantly lower than that of group C (p < 0.001). The MMSE at the postoperative 1, 2, and 5 days were significantly higher in Group O compared to Group C (p < 0.001). ASEM was similar between groups. Group O was subdivided according to the type of surgery applied with diagnosis, and there were no statistically significant between-group differences in terms of areas under the curve for the cerebral regional oxygen saturation. There was no between-group difference regarding the mean arterial pressure at any time perioperatively. The heart rate at 80, 90, 100, and 110 min intraoperatively was significantly higher in group C than in Group O. CONCLUSION: Intraoperative cerebral oxygenation monitoring can reduce patient mortality and morbidity by allowing early postoperative neurological evaluation to detect potential neurocognitive deficits.

Is music the food of the anesthesia in children?

Background: The noise in an operating room may have a detrimental effect on human cognitive functions, and it may cause perioperative anxiety with prolonged exposure. The aim of this study was to investigate the effects of music therapy and use of earplugs and normal noise level in the operating room under general anesthesia of pediatric patients on hemodynamic parameters and postoperative emergence delirium. Methods: One hundred and five pediatric patients were involved in this study. The patients were randomly divided into three groups. Group N was exposed to the ambient operating room noise, group S received earplugs from an independent anesthesiologist, and group M used a CD player. The preoperative anxiety levels of children were evaluated with the Modified Yale Preoperative Anxiety Scale (M-YPAS). Mean arterial pressure (MAP) and heart rate were recorded at 30-minute periods until the completion of surgery, end of surgery and postoperatively. During each measurement, noise level recordings were performed using sonometer. Pediatric Anesthesia Emergency Delirium (PAED) score was evaluated after postoperative extubation. Results: M-YPAS was similar between groups. The MAP at 30 and 60 min intraoperatively, at end of surgery, and at 5, 10, and 15 min postoperatively was significantly lower in group S than in group N. There were no differences in heart rate among the groups. Postoperative PAED score was not significantly different among the groups. Conclusions: The music therapy was not more effective than silence and operating noise room in reducing PAED score postoperatively in pediatric patients. Trial registration number: ClinicalTrials.gov Registry (NCT03544502).

The Effects of Glasgow Coma Scales and Bispectral Index on General Anaesthesia in Neurosurgery Patients.

OBJECTIVE: Monitorisation under anaesthesia is important for objective evaluation in intracranial surgery. We investigated general anaesthesia management performed by bispectral index (BIS) monitoring in patients who underwent surgery due to intracranial pathology with different Glasgow Coma Scales (GCS). METHODS: Forty-five patients who had been planned to undergo intracranial surgery under general anaesthesia were included in the study. Patients were divided into three groups according to GCS: Group I (n » 15) » 13-15 mildly injured; Group II (n » 15) » 9-12 moderately damaged; Group III (n » 15) » 3-8 severely damaged. Heart rate (HR), mean blood pressure, and use of anaesthetic agent were recorded. RESULTS: It was found that the consumption of the inhalation agent in Group III was lower than Groups I and II at all time intervals measured, and it was lower in Group II than Group I during the intervals at intraoperative 15th minute and up to 150th minute thereafter. The inhalation agent consumption rates according to the duration of anaesthesia were different between groups. The HR was significantly higher in Group III compared with Group II during the post-operative period. The mean arterial pressure was significantly lower in Group I than Group II preoperatively and at 5th, 10th, 15th, 20th, and 40th minute intra-operatively, whilst it was significantly lower in Group I than Group III preoperatively and 10th minute and 15th minute, intraoperatively. CONCLUSION: We found that in patients whose GCS was severely damaged and underwent intracranial surgery under general anaesthesia with BIS monitoring, the consumption of inhalation anaesthetic agent decreased, but opioid consumption did not change.
