The effects of active warming on perioperative inadvertent hypothermia in patients undergoing vitreoretinal surgery under local anesthesia.

Purpose: Perioperative inadvertent hypothermia (PIH) is the decrease in core temperature below 36°C. We aimed to assess whether PIH develops in patients operated under local anesthesia (ULA) for vitreoretinal surgery in the operating room and investigate active warming efficacy. Methods: Seventy-two patients were divided into two groups: Group 1 contained unwarmed patients (n = 36), and Group 2, warmed patients (n = 36). The core temperatures, heart rate (HR), and mean arterial pressure (MAP) of the patients were measured at the beginning of surgery, after 20 min, 40 min, 1 h, at the end of the operation, and during the postoperative period. Results: PIH incidence was 44.6% in Group 1, whereas no hypothermia was observed in Group 2. Patient temperatures at 20 min (P = 0.001), 40 min (P < 0.001), 1 h (P < 0.001), the end of the operation (P < 0.001), and the postoperative period (P < 0.001) were significantly higher in Group 2 than in Group 1. Patient HRs at the end of the operation and during the postoperative period were significantly lower in Group 2 (P = 0.005) than in Group 1 (P < 0.001). The intraoperative 40th (P = 0.044) and 60th (P < 0.001) minutes, end of operation (P < 0.001), and postoperative MAP (P < 0.001) values of Group 1 were significantly higher than those of Group 2. Conclusion: PIH may develop in patients operated ULA, especially with a low ambient temperature. Actively warming may help prevent the harmful effects of PIH.

Effect of initial antifungal therapy on mortality among patients with bloodstream infections with different Candida species and resistance to antifungal agents: A multicentre observational study by the Turkish Fungal Infections Study Group.

This study aimed to describe the effect of initial antifungal therapy on patient mortality and to detail the current distribution and resistance patterns of Candida spp. among patients with candidaemia. A prospective observational study was performed among consecutive patients with candidaemia from 10 Turkish medical centres between January 2015 and November 2018. The primary outcome was 10-day mortality. Species were identified using MALDI-TOF/MS. A total of 342 patients with candidaemia were included, of which 175 (51.2%) were male and 68 (19.9%) were aged <18 years. The most common species were Candida albicans (47.4%), Candida parapsilosis (26.6%), Candida tropicalis (9.6%) and Candida glabrata (7.6%). Among all Candida spp., the 10-day case fatality rate (CFR) was 32.2%. The CFR was highest in patients with C. albicans (57.3%) and lowest in patients with C. parapsilosis (21.8%). The resistance rate to fluconazole was 13% in C. parapsilosis, with no significant effect on mortality. No resistance to echinocandins was detected. In the multivariate analysis, being in the ICU [OR = 2.1 (95% CI 1.32-3.57); P = 0.002], renal failure [OR = 2.4 (1.41-3.97); P = 0.001], total parenteral nutrition [OR = 2 (1.22-3.47); P = 0.006], C. albicans infection [OR = 1.7 (1.06-2.82); P = 0.027] and echinocandin as primary agent [OR = 0.6 (0.36-0.99); P = 0.047] were significantly associated with mortality. Candidaemia is a deadly infection. Fluconazole resistance is emerging, although it was not significantly related to mortality. Using an echinocandin as the primary agent could be life-saving.
