[Topical anesthesia without the use of an anesthesiologist in adult outpatient cataract surgery: Assessment of selection criteria on consultation, report of 248 cases]. / L'anesthésie topique sans recours à un médecin anesthésiste dans la chirurgie de la cataracte ambulatoire de l'adulte : évaluation des critères de sélection en consultation, à propos de 248 cas.

INTRODUCTION: This work aims to evaluate selection criteria used during the cataract surgery scheduling visit, to choose whether or not there will be an anesthesiologist available during the surgery, depending upon the patient's comorbidities. MATERIALS AND METHODS: Retrospective study performed in 2016 in Angers university medical center. Two groups were established on the cataract surgery scheduling visit, based on patients' comorbidities and vital signs (blood pressure, heart rate). One group of patients were operated with topical anesthesia, with the anesthesia team, the other one only with blood pressure and heart rate monitoring, with, if needed, a written protocol of sedation or blood pressure control, which could be administrated by a circulating nurse. Those two groups were compared in terms of postoperative complications, intraoperative pain and postoperative visual acuity. RESULTS: 248 surgeries were performed on 185 individual patients, with 108 under stand-alone topical anesthesia, and 135 under anesthetist-monitored topical anesthesia. No significant difference was demonstrated between the two groups, in terms of complications, intraoperative pain or visual acuity outcomes. DISCUSSION: This study allows us to assess selection criteria used in our hospital to determine which patients can undergo cataract surgery under topical anesthesia without the anesthesia team. This procedure lowers organizational constraints while still insuring patient safety. Some patients still probably need an anesthesiologist present, such as those with an unstable disease or risk of agitation, in order to optimize the medications administered during surgery.

Bacterial keratitis treated by strengthened antibiotic eye drops: An 18 months review of clinical cases and antibiotic susceptibilities.

PURPOSE: To describe, in patients treated for infectious keratitis, the microorganisms identified and their antibiotic susceptibility over a period of 18 months. METHOD: Retrospective, descriptive, non-comparative study. Medical and biological data were extracted from the patients' file treated with strengthened antibiotic eye drops at Angers University Hospital between January 2015 and June 2016. The main elements noted were the bacteria involved and their susceptibility to antibiotics. Patients' visual acuity at the start and end of treatment was compared. RESULTS: Forty-eight patients were included. Almost one bacterium was identified in 31 patients, totalling 43 pathogens of 24 different species. The most frequently found microorganisms were Gram-positive cocci (55.8%), including Staphylococcus Aureus (14.0%) and Epidermidis (14.0%). All Gram-negative bacilli amounted to 30.2% of the identified bacteria, including 9.3% of Pseudomonas aeruginosa. None of the Gram-positive cocci were resistant to vancomycin and all Gram-negative bacilli were susceptible to ceftazidime and amikacin. Following treatment with at least one of the three antibiotic eye drops produced by our pharmacy (amikacin at 50mg/mL, ceftazidime at 50mg/mL and vancomycin at 25mg/mL), patients' visual acuity was significantly improved (P=0.043). CONCLUSION: The study helped identify the bacterial ecology of patients admitted for infectious keratitis. Among the bacteria identified, none were found to be resistant to any of the three strengthened antibiotic eye drops produced by the hospital pharmacy. These eye drops allowed for a rapid and effective treatment of patients and the improvement of their visual acuity before even identifying the bacteria.
