Background:In contemporary practice, acute mesenteric ischemia (AMI) remains a serious cause of morbidity and mortality in abdominal emergencies.Objectives:We report the measurement of peritoneal fluid potassium and pH on a small series of rats that developed extensive AMI following the surgical ligation of superior mesenteric vessels and compare the results with control groups.Materials and Methods:A total of 32 rats were used in our study. They were divided into four groups with eight rats in each one and received following treatments: group I (G-I), 60-minute controls; group II (G-II), 120-minute controls; group III (G-III), 60-minute cases; and group IV (G-IV), 120-minute cases. In case groups, the small bowel mesenteric root was double-ligated and an arrow single-lumen central venous catheter was passed through the skin to the peritoneum. In control groups, the catheter was placed without any intervention. Postoperatively, peritoneal lavage was performed at 60 (G-I, G-III) and 120 minutes (G-II, G-IV).Results:The mean peritoneal potassium values were 1.3 ± 0.3, 1.97 ± 1.06, 2.14 ± 0.89, and 3.28 ± 0.66 mmol/L in G-I, G-II, G-III, and G-IV, respectively. There were significant differences between G-III and G-IV (P = 0.002), between G-I and G-III (P = 0.024), and between G-II and G-IV (P = 0.001). The mean values of peritoneal fluid pH were 7.1 ± 0.26, 6.82 ± 0.22, 6.66 ± 0.16, and 6.78 ± 0.04 in G-I, G-II, G-III, and G-IV, respectively, which indicated significant differences between G-I and G-III (P = 0.001) and between G-II and G-IV (P = 0.018). There was a significant correlation between peritoneal fluid potassium and intestine ischemic grade (F = 4.77, P = 0.048)ConclusionsOur findings show that for early detection of bowel ischemia, an evaluation of intraperitoneal potassium and pH was useful and with prolongation of ischemia, potassium changes were more significant.
Background On March 11, 2020, the World Health Organization (WHO) announced the COVID-19 outbreak as a new pandemic. In the meantime, plastic surgeons postponed their appointments due to the fair and rational allocation of medical supplies. These limitations made all junior and senior residents perform operations only on traumatic patients rather than those needing reconstructive procedures. This study aims to determine the effects of the COVID-19 pandemic on plastic surgery training programs in Iran. Also, the number of canceled surgeries will be determined to see the effects of the pandemic on the patients. Methods This retrospective case study considers a six-month timeframe in two consecutive years before and after the COVID-19 pandemic. For this purpose, the researchers evaluated the number of surgeries, types of procedures, age distribution, and gender distribution. The training program data of plastic surgery residents were collected from their logbooks and then analyzed in IBM SPSS Statistics 26. Differences were considered significant if p < 0.05 at a 95% confidence level. Results The total number of surgeries decreased by 23.5% after the COVID-19 outbreak (p < 0.05). There was a 29.9% reduction in trauma cases, -78.9% in aesthetic surgeries, -17.7% in reconstructive surgeries, -51.8% in craniofacial surgeries, and -59.5%in microscopic surgeries for each resident. Conclusions This study provides an insight into the severity of the pandemic effects on the plastic surgery training programs and the patients. The reduced number of surgeries led to a depletion in surgical skills training. These effects will not wear off immediately after the pandemic; therefore, it is necessary to observe whether the pandemic will have any lasting effects on this subspecialty.
BACKGROUND The demand for facial plastic surgery has dramatically been increased in recent years. Over the last decade, numerous methods have been improved for facelift surgery. Despite these modifications, skin excision technique has not changed significantly. In this study, authors have tried to introduce a new technique regarding skin excision at the initial step of facelift surgery. METHODS A prospective study from 2012 to 2017 on 52 patients was carried out to apply a new technique for facelift ‘’Prefabricated skin excision method’’ for all eligible patients undergoing facelift surgery. The skin calling for excision was marked by the surgeon, and then, an analgesic drug was administered. Then, excision of the marked part of the skin was performed and afterward the dissection of the superficial musculoaponeurotic system (SMAS) was performed with the direct exposure. RESULTS All patients were female, and 50 (96.1%) cases were primary face lift and 2 (3.9%) cases were secondary. There were no complications among the patients. CONCLUSION Facilitating the manipulation of deep layer, using this technique led to the further exposure of the surgical site, and more preferable hemostasis was achieved as well.
