Öğe Successful ımplementation of a bundle strategy to prevent ventilator-associated pneumonia in aneonatal ıntensive care unit(Oxford unıv press, great clarendon st, oxford ox2 6dp, england, 2018) Gokce, Ismail Kursad; Kutman, Hayriye Gozde Kanmaz; Uras, Nurdan; Canpolat, Fuat Emre; Dursun, Yasemin; Oguz, Serife SunaBackground: We aimed to investigate the effectiveness of evidence-based bundle that we developed to reduce ventilator-associated pneumonia (VAP) rates and to assess the degree of compliance rates to this strategy in a tertiary neonatal intensive care unit. Methods: This before-after prospective cohort trial divided into two periods was conducted. All neonates requiring ventilation were enrolled in the study. VAP incidence, compliance rates to bundle components and the contribution of each bundle component to VAP rates were compared between the periods. Results: Throughout the study period, 13 VAP episodes were observed. Full adherence to all six components of the bundle doubled in the active-bundle period (12.8 vs. 24.3%, p<0.01). The mean VAP rate decreased from 7.33/1000 to 2.71/1000 ventilator days following intervention (p = 0.083).Öğe Comparison of intravenous ibuprofen and acetaminophen for postoperative multimodal pain management in bariatric surgery: A randomized controlled trial(ELSEVIER SCIENCE INC, 360 PARK AVE SOUTH, NEW YORK, NY 10010-1710 USA, 2018) Şanlı, Mukadder; Kırteke, Ramazan; Yoloğlu, SaimStudy objective: Multimodal analgesic strategies are recommended to decrease opioid requirements and opioid-induced respiratory complications in patients undergoing laparoscopic bariatric surgery. Recent studies have demonstrated that intravenous ibuprofen decreases opioid consumption compared with placebo. The primary aim of this study was to compare the effect of intravenous ibuprofen and intravenous acetaminophen on opioid consumption. We also aimed to compare postoperative pain levels and side effects of the drugs. Design: Randomized, double-blinded study. Setting: University hospital. Patients: Eighty patients, aged 18-65 years, (ASA physical status undergoing laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass surgery were included in this study. Interventions: Patients were randomized to receive 800 mg ibuprofen or 1 g acetaminophen intravenously every 6 h for the first 24 h following surgery; in addition, patient-controlled analgesia with morphine was administered. Measurements: Postoperative morphine consumption in the first 24 h, visual analog scale (VAS) pain scores at rest and with movement, and opioid related side effects were assessed. In addition, time to passage of flatus, surgical complications, lengths of intensive care unit and hospital stay, and laboratory parameters were recorded. Main results: The mean morphine consumption was 23.94 +/- 13.89 mg in iv ibuprofen group and 30.23 +/- 13.76 mg in the acetaminophen group [mean difference: -6.28 (95% CI, -12.70, 0.12); P = 0.055]. The use of intravenous ibuprofen was associated with reduction in pain at rest (AUC, 1- to 24-h, P < 0.001 and 12- to 24-h, P = 0.021) and pain with movement (AUC, 1-24, 6-24, and 12-24 h, P < 0.001). Intravenous ibuprofen was well tolerated with no serious side effects except dizziness. Conclusions: Intravenous ibuprofen did not significantly reduce opioid consumption compared to intravenous acetaminophen; however, it reduced the severity of pain. Intravenous ibuprofen may be a good alternative to intravenous acetaminophen as part of a multimodal postoperative analgesia in patients undergoing bariatric surgery.Öğe Changes in melatonin, cortisol, and body temperature, and the relationship between endogenousmelatonin levels and analgesia consumption in patients undergoing bariatric surgery(Sprınger, 233 sprıng st, new york, ny 10013 usa, 2018) Altunkaya, Neslihan; Erdogan, Mehmet Ali; Ozgul, Ulku; Sanli, Mukadder; Ucar, Muharrem; Ozhan, Onural; Sumer, Fatih; Erdogan, Selim; Colak, Cemil; Durmus, MahmutBackground Melatonin has analgesic, anti-inflammatory, sedative, and anxiolytic properties. However, the relationship between endogenous melatonin levels and postoperative analgesic requirements has not been well elucidated in patients undergoing bariatric surgery. We studied endogenous melatonin levels, cortisol levels, body temperatures, and the relationship between the level of endogenous melatonin and postoperative morphine consumption. Methods The trial was conducted among 30 patients who were scheduled for laparoscopic bariatric surgery. Their ages were between 18 and 65 years and their BMIs were above 40 kg/m(2). Secretion of melatonin, cortisol, and body temperature was monitored before the anesthetic induction, at 2 h intraoperatively, and at 2, 6, 10, (2:00 A.M.) and 24 h postoperatively. For each patient, morphine consumption was assessed at postoperative visits. The primary outcomes were to measure endogenous melatonin levels and to examine the relationship between these levels and morphine consumption. The secondary outcome was to observe the changes in cortisol and body temperature. Results There was a significant decrease in melatonin levels when preoperative melatonin levels were compared with intraoperative and all postoperative follow-up periods (p < 0.05). When the correlation between plasma melatonin levels and the postoperative morphine consumption of the patients was inspected, there was a significant correlation in all of the follow-up periods (p < 0.05). When preoperative cortisol levels were compared with intraoperative and postoperative cortisol levels, there was a significant difference in the follow-up periods, except two periods (p < 0.05). Body temperatures were similar in all measurement periods. Conclusions Endogenous melatonin secretion was significantly decreased in the intraoperative and postoperative periods. Furthermore, there was a significant inverse correlation between changes in endogenous melatonin levels and morphine consumption.Öğe Dexpanthenol'ün iskemi-reperfüzyonun neden olduğu karaciğer hasarına koruyucu etkisi(2018) Ucar, M.; Aydogan, MS; Vardi, N.; Parlakpınar, H.Objective. We aimed to investigate the protective and therapeutic effects of dexpanthenol (DXP) on liver injuries induced by ischemia-reperfusion (IR) in an in vivo rat model. Methods. Thirty-two rats were randomly divided into 4 experimental groups (n = 8 in each group: Sham, IR, DXP, and DXP+IR. DXP (500 mg/kg) was intraperitoneally administered for 30 min before 60 min of ischemia, followed by 60 min of reperfusion to rats in the DXP and DXP+IR groups. All rats were euthanized on day 10 to evaluate immunohistopathological changes as well as tissue levels of oxidants and antioxidants. Results. IR decreased total glutathione (tGSH) levels in IR group when compared to the Sham group. DXP supplementation to IR group significantly ameliorated tGSH levels (P < .05). IR also elevated myeloperoxidase production compared to the Sham group, whereas DXP treatment prevented these hazardous effects. However, plasma superoxidedismutase, catalase, and malondialdehyde levels did not differ between the DXP+IR than the IR rats. Histologic tissue damage was reduced in the DXP and DXP+IR group. Conclusion. Liver IR is an inevitable problem during liver surgery. Our results suggested that DXP pretreatment suppressed oxidative stress and increased antioxidant levels in a rat model of liver IR.
