Comparison of demographic and clinical characteristics between pandemic and pre-pandemic period in non-COVID intensive care units: a retrospective study.

BACKGROUND: A major problem of the coronavirus pandemic is the increase of patients requiring intensive care unit (ICU) sup-port in an extremely limited period of time. As a result, most countries have prioritized coronavirus disease 2019 (COVID-19) care in ICUs and take new arrangements to increase hospital capacity in emergency department and ICUs. This study aimed to evaluate the changes in the number, clinical and demographic characteristics of patients hospitalized in non-COVID ICUs during the COVID-19 pandemic period compared to the previous year (pre-pandemic period), and to reveal the effects of the pandemic. METHODS: Hospitalized patients in non-COVID ICUs of our hospital between 11 March 2019 and 11 March 2021 were included in the study. The patients were divided into two groups according to date of the start of the COVID period. Patient data were scanned and recorded retrospectively from hospital information system and ICU assessment forms. Information regarding demographics (age and gender), comorbidities, COVID 19 polymerase chain reaction result, place of ICU admission, the diagnoses of patients admitted to ICU, length of ICU stay, Glasgow coma scale and mortality rates, and the Acute Physiology and Chronic Health Evaluation II score were collected. RESULTS: A total of 2292 patients were analyzed, including 1011 patients (413 women and 598 men) in the pre-pandemic period (Group 1) and 1281 patients (572 women and 709 men) in the pandemic period (Group 2). When the diagnoses of patients admitted to ICU were compared between the groups, there was a statistically significant difference between post-operation, return of spon-taneous circulation, intoxication, multitrauma, and other reasons. In the pandemic period, the patients had a statistically significant longer length of ICU stay. CONCLUSION: Changes were observed in the clinical and demographic characteristics of patients hospitalized in non-COVID-19 ICUs. We observed that the length of ICU stay of the patients increased during the pandemic period. Due to this situation, we think that intensive care and other inpatient services should be managed more effectively during the pandemic.

The effects of positive end-expiratory pressure (PEEP) application on optic nerve sheath diameter in patients undergoing laparoscopic cholecystectomy: a randomized trial.

BACKGROUND: Positive end-expiratory pressure (PEEP) can overcome respiratory changes that occur during pneumoperitoneum application in laparoscopic procedures, but it can also increase intracranial pressure. We investigated PEEP vs. no PEEP application on ultrasound measurement of optic nerve sheath diameter (indirect measure of increased intracranial pressure) in laparoscopic cholecystectomy. METHODS: Eighty ASA I-II patients aged between 18 and 60 years scheduled for elective laparoscopic cholecystectomy were included. The study was registered in the Australian New Zealand Clinical Trials (ACTRN12618000771257). Patients were randomly divided into either Group C (control, PEEP not applied), or Group P (PEEP applied at 10 cmH20). Optic nerve sheath diameter, hemodynamic, and respiratory parameters were recorded at six different time points. Ocular ultrasonography was used to measure optic nerve sheath diameter. RESULTS: Peak pressure (PPeak) values were significantly higher in Group P after application of PEEP (p = 0.012). Mean respiratory rate was higher in Group C at all time points after application of pneumoperitoneum (p < 0.05). The mean values of optic nerve sheath diameters measured at all time points were similar between the groups (p > 0.05). The pulmonary dynamic compliance value was significantly higher in group P as long as PEEP was applied (p = 0.001). CONCLUSIONS: During laparoscopic cholecystectomy, application of 10 cmH2O PEEP did not induce a significant change in optic nerve sheath diameter (indirect indicator of intracranial pressure) compared to no PEEP application. It would appear that PEEP can be used safely to correct respiratory mechanics in cases of laparoscopic cholecystectomy, with no significant effect on optic nerve sheath diameter.

Comparison of Intraabdominal and Trocar Site Local Anaesthetic Infiltration on Postoperative Analgesia After Laparoscopic Cholecystectomy.

OBJECTIVE: This study aimed to compare the efficacy of local anaesthetic infiltration to trocar wounds and intraperitoneally on postoperative pain as a part of a multimodal analgesia method after laparoscopic cholecystectomies. METHODS: The study was performed on 90 ASA I-III patients aged between 20 and 70 years who underwent elective laparoscopic cholecystectomy. All patients had the same general anaesthesia drug regimen. Patients were randomized into three groups by a closed envelope method: group I (n=30), trocar site local anaesthetic infiltration (20 mL of 0.5% bupivacaine); group II (n=30), intraperitoneal local anaesthetic instillation (20 mL of 0.5%) and group III (n=30), saline infiltration both trocar sites and intraperitoneally. Postoperative i.v. patient controlled analgesia was initiated for 24 h. In total, 4 mg of i.v. ondansetron was administered to all patients. Visual analogue scale (VAS), nausea and vomiting and shoulder pain were evaluated at 1., 2., 4., 8., 12., 24. hours. An i.v. nonsteroidal anti-inflammatory drug (NSAID) (50 mg of dexketoprofen) as a rescue analgesic was given if the VAS was ≥5. RESULTS: There were no statistical significant differences between the clinical and demographic properties among the three groups (p≥0.005). During all periods, VAS in group I was significantly lower than that in groups II and III (p<0.001). Among the groups, although there was no significant difference in nausea and vomiting (p=0.058), there was a significant difference in shoulder pain. Group III (p<0.05) had more frequent shoulder pain than groups I and II. The total morphine consumption was higher in groups II and III (p<0.001 vs p<0.001) than in group I. The requirement for a rescue analgesic was significantly higher in group III (p<0.05). CONCLUSION: Trocar site local anaesthetic infiltration is more effective for postoperative analgesia, easier to apply and safer than other analgesia methods. Morphine consumption is lesser and side effects are fewer; therefore, this method can be used as a part of common practice.

Endovenous laser ablation with 980-nm diode laser: early and midterm results.

OBJECTIVE: Endovenous laser ablation (EVLA) is an efficient method to treat incompetent great saphenous veins (GSV) with high occlusion rates. The aim of this prospective study is to demonstrate the treatment outcomes of EVLA of incompetent GSV with a 980-nm diode laser in an ambulatory setting. BACKGROUND DATA: EVLA of the incompetent GSV with a 980-nm diode laser appears to be an extremely safe technique. There are several treatment alternatives available. Among the emerging techniques, EVLA is one of the most promising. METHODS: Ninety eight patients (103 limbs) with symptomatic varicose veins secondary to GSV insufficiency treated with 980-nm EVLA were prospectively studied. In all patients, laser energy was administered with constant pullback of fiberoptic laser catheter under tumescent anesthesia. The patients were assessed and followed by clinical examination and venous duplex ultrasonography. Pain scores of the patients from discharge to their first follow-up visit (7 days) were recorded by using visual analog scale (VAS). Patient satisfaction was assessed and recorded at 6 month follow-up. RESULTS: All patients tolerated EVLA procedure well, and were discharged from hospital on the same day with ablation procedure. The overall success rate was 97.5% in 98 patients. Mean length of measured treated vein segment was 29.93±6.36 cm. Mean applied total energy was 2006.24±480.16 J. Major complications such as deep vein thrombosis and skin burns were not seen. Most of the complications were minor and improved quickly. All patients returned to daily activities within 2 days. CONCLUSIONS: EVLA of the GSV insufficiency using 980-nm diode laser is an effective and safe technique with a high patient satisfaction rate. The advantages of the procedure are that it is performed as an outpatient procedure, provides early mobilization, causes minimal cessation of daily activities, and avoids classic surgical complications.
