Comparison between magnesium sulfate and dexmedetomidine in controlled hypotension during functional endoscopic sinus surgery

AbstractBackground and objectivesIt is crucial to decrease bleeding during functional endoscopic sinus surgery. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on the visibility of the surgical site.Methods60 patients aged between 18 and 65 years were enrolled. In the magnesium sulfate group (Group M), patients were administered 40mg/kg magnesium sulfate in 100mL saline solution over 10min as the intravenous loading dose 10min before induction, with a subsequent 10–15μg/kg/h infusion during surgery. In the dexmedetomidine group (Group D), patients were administered 1μg/kg dexmedetomidine in 100mL saline solution as the loading dose 10min before surgery and 0.5–1μg/kg/h dexmedetomidine during surgery. Deliberate hypotension was defined as a mean arterial pressure of 60–70mmHg.ResultsBleeding score was significantly decreased in Group D (p=0.002). Mean arterial pressure values were significantly decreased in Group D compared to that in Group M, except for the initial stage, after induction and 5min after intubation (p<0.05). The number of patients who required nitroglycerine was significantly lower in Group D (p=0.01) and surgeon satisfaction was significantly increased in the same group (p=0.001). Aldrete recovery score ≥9 duration was significantly shorter in Group D (p=0.001). There was no difference between the two groups in terms of recovery room verbal numerical rating scale.ConclusionsDexmedetomidine can provide more effective controlled hypotension and thus contribute to improved visibility of the surgical site

Self-reported antibiotic stewardship and infection control measures from 57 intensive care units: An international ID-IRI survey

We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases-International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (similar to 5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%-90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&amp;50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs' implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.

Obstetric Patients Admitted to Anesthesiology İntensive Care Unit: A 10-Year Retrospektive Review

Abstract: Aim: To assess obstetric patients treated in anesthesiology intensive care unit. Methods: We retrospectively screened 269 patients. In all patients, gestational age, mode of delivery, parity, referring clinic, previous medical disease, diagnosis at admission, APACHE II Score and GCS score were recorded. Clinical course in intensive care unit and cause of death in non-survivors were recorded. Results: The percentage of obstetric patients treated in intensive care unit was 9.4% with a mortality rate of 3.7%. Preeclampsia, eclampsia and HELLP syndrome were leading causes for intensive care unit admission. Conclusion: Most common cause of death was postpartum bleeding and its complication.</p
