Objective: Low tidal volume (VT) and lung protective ventilation (LPV) are recommended to prevent lung injury associated with invasive mechanical ventilation (IMV). Present study aimed to determine the patients with risk of high VT application, whether VT calculated according ideal body weight (IBW) values are suitable for the recommended (6-8 mL/kg) and whether a questionnaire on the issue contributes to IMV suitable for LPV.Materials and Methods: Present study is conducted as a multicenter point - prevalence study in the intensive care units of three hospitals in Bursa. Non-ARDS patients receiving IMV and patients who were older than 18 years were included in the study. IMV parameters and demographic data of the patients were collected. Then, the physicians responsible of ventilatory management completed a questionnaire about LPV strategies and VT values required according to the IVA were shown. After 24 hours, mechanical ventilation parameters were re-collected. Body mass index (BMI), average tidal volume applied [VTmean = minute volume (MV)/respiratory rate (RR)] and VTmean for IBW (VTmean/IBW) values were calculated.Results: Fifty-six patients were included in the study. There were 33 male patients (58.9%) and the mean age of the patients was 65.43 +/- 18.87 years. The mean BMI of the patients was 27.84 +/- 7.0. The most commonly used ventilation mode was synchronized intermittent mandatory ventilation (75%). The VTmean was 549.32 +/- 151.00 mL (VTmean/IBW =9.31 +/- 3.07 mL/kg). According to VTmean/IBW, for the use of large VTs, being female (10.77 +/- 2.74 mL/kg) and having BMI >= 30 (10.82 +/- 3.80 mL/kg) posed significantly higher risk than being male (8.31 +/- 2.91 mL/kg) and having BMI <30 (8.67 +/- 2.47 mL/kg) (p=0.002, p=0.015 respectively). The results showed a significant decrease (p=0.026) in VTmean/IBW (8.81 +/- 3.49 mL/kg) values after the physicians completed LPV questionnaire and were shown the VT values (predicted by IBW).Conclusion: VTmean/IBW values were found to be higher than 6-8 mL/kg, the recommended value for LPV. Ventilation with high VT was associated with female gender and having a BMI of >= 30. Completing the LPV questionnaire and seeing the VT values (predicted by IBW) contributed to the number of the patients ventilated with VT values suitable LPV.
A comparision of the effect of sugammadex on the recovery period and postoperative residual block in young elderly and middle-aged elderly patients
(Galenos Yayıncılık, 2015-10-20) Yazar, Emine; Yılmaz, Canan; Karasu, Derya; Apaydın, Yılmaz; Sayan, Halil Erkan; Bilgin, Hülya; Bayraktar, Selcan; Uludağ Üniversitesi/Tıp Fakültesi/Anesteziyoloji ve Reanimasyon Anabilim Dalı.; 0000-0001-6639-5533; A-7338-2016; 6701663354; 34879358300
Background: The importance of the characteristics of anesthesia and postoperative residual curarization (PORC) in the elderly population should be a growing concern in this century. Aims: To investigate the effect of sugammadex on the duration of the recovery from neuromuscular blocking agents and postoperative residual curarization in the young elderly and middle-aged elderly patients who underwent elective laparoscopic cholecystectomy, followed by a train of four (TOF) watch monitorization. Study Design: Prospective clinical trial study. Methods: Sixty patients over the age of 65 with American Society of Anesthesiologists I-III were divided into two groups according to their age (65-74 years old and >= 75 years old). Patients received sugammadex (2.0 mg/kg iv) at the reappearance of the second twitch of the TOF as an agent for reversal of neuromuscular blockage at the end of surgery. Patients were extubated at the time of TOF >= 0.9. The patients' TOF responses were evaluated with regards to PORC in at the 5th minute and were followed up for one hour in the recovery room. Reintubation was applied for those patients who developed PORC and had peripheric oxygen saturation <90% despite being given 6 L oxygen per min with a face mask. Results: The onset time of neuromuscular blocking agent and time from T-2 to achieve TOF ratio 90% (the duration of sugammadex effect) or over were found to be longer in the middle-aged elderly group than in the young elderly group. A statistically significant relationship was found between age and the duration of TOF ratio to reach 0.9 in the same direction. The PORC incidence and rate of reintubation were found to be 1.7% in all patients. Conclusion: In our opinion, it is necessary to remember that the duration of sugammadex effect on the recovery period is prolonged for patients who are aged >= 75 years compared to patients aged between 65-74 years.
Prevalence of pressure ulcers in hospitalized adult patients in Bursa, Turkey: A multicentre, point prevalence study
(Wiley, 2020-12) Sayan, Halil Erkan; Asan, Ali; Girgin, Nermin Kelebek; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Anesteziyoloji ve Reanimasyon Anabilim Dalı.; DTU-3148-2022; 55663009300
Rationale, aims, and objectives: Pressure ulcers (PUs), which are preventable complications, increase the cost of health care and the risk of prolonged hospital stay, as well as morbidity and mortality. In this study, we aimed to describe the prevalence, clinical features, and risk factors for PUs among hospitalized patients. Method: This study was cross-sectional and conducted over a single day in all the care units. Data were recorded on a patient observation form that included demographic data, diagnosis of admission to the hospital or intensive care unit (ICU), comorbidity and chronic diseases, location, stage of PU, and Braden Scale score. Acute physiology and chronic health evaluation (APACHE) II score, Glasgow coma score (GCS), PaO2/FiO2 ratio, and albumin level were recorded for ICU patients. Results: A total of 1548 adult patients participated in the study. Of these patients, 177 (11.43%) had PU. The patients with PU had more advanced age, lower body mass index (BMI), and longer duration of hospital and ICU stay (for all P =.001). Evaluation of PU in the first 24 hours after hospital admission and the last PU evaluation time also showed a significant effect (both P =.001). Braden Scale score less than or equal to 13 in the first evaluation after hospital admission increased the risk of PU. Albumin was 2.78 ± 0.57 gm/dL in ICU patients, and albumin level was significantly lower in patients with PU (P =.001). PUs were located mainly in the sacrum (47.59%) and were classified as stage II (42.76%) for all patients. Conclusions: The prevalence of PU is related to the age and severity of patient clinical status, as predicted by the Braden Scale score and APACHE II score, and length of hospital and ICU stay. Low albumin level is also related to development of PUs in ICU patients.
