Objective: The aim of this study was to examine the impact of performing surgeries with necessary precautions and to evaluate demographic characteristics of operated patients during novel coronavirus-2019 (COVID-19) pandemic and the infection rates during hospitalization and within 14 days after surgery. Material and Methods: Between March 15th, 2020 and April 30th, 2020, a total of 639 patients who had been operated on in our center were retrospectively analyzed. According to the triage system, the surgical procedures were classified as emergency, time-sensitive, and elective procedures. Data including age, sex, indication for surgery, the American Society of Anesthesiologists (ASA) class, pre- and postoperative symptoms, the presence and/or absence of reverse transcriptase-polymerase chain reaction (RT-PCR) test result, type of surgery, surgical site, and documented COVID-19 infections during hospitalization and within 21 days after surgery were recorded. Results: Of the patients, 60.4% were males and 39.6% were females with a mean age of 43.08 +/- 22.68 years. Malignancy was the most common indication for surgery (35.5%), followed by trauma (29.1%). The abdominal area and head and neck region were the most frequent surgical sites in 27.4% and 24.9% of the patients, respectively. Of all surgical procedures, 54.9% were emergency and 43.9% were time-sensitive procedures. Of the patients, 84.2% were in ASA Class I-II while 15.8% patients were in ASA Class III, IV and V. General anesthesia was the most common anesthesia type in 83.9% of the patients. The overall rate of COVID-19 infection was 0.63% in the preoperative period. The rate of COVID-19 infection during and after surgery was 0.31%. Conclusion: With similar infection rates to the general population, surgeries of all types can be performed safely taking preventive measures in the pre- and postoperative period. It would be wise to perform surgical treatment without delay in patients with an increased risk for mortality and morbidity in accordance with strict infection control principles.

OBJECTIVE: Laparoscopic surgery has been suggested to pose a risk of infection to the surgical team due to aerosol and gas leakage during the coronavirus (COVID-19) pandemic. However, there have been no studies on the risk of gas and aerosol leakage in laparoscopic surgery. We aimed to answer the question "Is the aerosol and gas leakage in laparoscopy is hazardous in terms of coronavirus infection?" with this study. MATERIALS AND METHODS: In this study, gas and aerosol leaks were documented by simulating the entry and exit maneuvers from a trocar during laparoscopic surgery using a high-speed camera, fog, and laser in a model representing the abdomen. RESULTS: The maximum gas and aerosol leakage were found during wet gauze extraction from the 10 mm trocar, and its velocity reached 7.5 m/s. The fastest aerosol leakage rate was observed when a 5 mm grasper was extracted from the 5 mm trocar. The results of the subsequent trials were consistent with these values. CONCLUSIONS: Higher leakage speeds were observed than the velocity of the exhaled air in a resting person. The surgical crew members, who work very close to the trocars and each other, are at serious risk of infection with COVID-19 which can spread as fast as exhalation speed through trocars. Since there is an evident risk of infection for the surgical crew from laparoscopic surgery of a patient whose intraabdominal fluids are infected with COVID-19, patients must be evaluated elaborately for COVID-19 preoperatively and infected patients should undergo surgery conventionally.

Objective: Maxillofacial trauma (MFT) is a frequent presentation in the emergency department (ED) which requires a multidisciplinary approach. Although, its etiology and diversity of injuries are almost similar worldwide, the causes may differ among the countries depending on the sociocultural and environmental factors and local traffic regulations. This study aims to evaluate etiologies of maxillofacial traumas (MFTs) in ED and to compare etiologies of MFTs during COVID-19 pandemic with the previous year. Patients and Methods: Totally 84 (61 males, 23 females) patients admitted to ED of our center with MFT between March 15th - April 30th, 2020 were included. The control group consisted of 148 (112 males, 36 females) MFT patients admitted to ED in the previous year (March 15th-April 30th, 2019). Data including age, sex, cause of trauma, treatment, and COVID-19 infection status within 14 days after ED admission were compared between groups. Results: Mean age was 31.88 +/- 2.53 years in the patient group and 31.40 +/- 1.74 years in the control group. Number of patients admitted to ED with MFTs decreased by 43.3% during pandemic compared to the previous year. Majority of MFTs occurred at home, followed by public places, traffic, and workplaces in both time periods. During pandemic, the rate of home accidents increased and MFTs occurred in the public places decreased. Conclusion: COVID-19 pandemic-mandated social restrictions lead to a decrease in the number of MFTs. However, home accidents are the main cause of MFTs. Spread of COVID-19 infection in the hospital setting can be minimized with necessary precautions.
