Design: Prospective examination of out of hospital cardiac arrests by using the Utstein style and necropsy reports. World Health Organization criteria were applied to determine the number of sudden cardiac deaths. Results: Of 300 OHSCDs, 197 (66%) in men, mean age (SD) 68 (14) years, 234 (78%) occurred at home. The emergency medical services (EMS) attended 279 (93%). Rhythm on EMS arrival was ventricular fibrillation (VF) in 75 (27%). The call to response interval (CRI) was mean (SD) 8 (3) minutes. Among patients attended by the EMS, 9.7% were resuscitated and 7.2% survived to leave hospital alive. The CRI for survivors was mean (SD) 5 (2) minutes and for non-survivors, 8 (3) minutes (p , 0.001). Ninety one (30%) OHSCDs were witnessed; of these 91 patients 48 (53%) had VF on EMS arrival. The survival rate for witnessed VF arrests was 20 of 48 (41.7%): all 20 survivors had VF as the presenting rhythm and CRI ( 7 minutes. The European age standardised incidence for OHSCD was 122/100 000 (95% confidence interval 111 to 133) for men and 41/100 000 (95% confidence interval 36 to 46) for women. Conclusion: Despite a 37% reduction in heart attack mortality in Ireland over the past 20 years, the incidence of OHSCD in Belfast has not fallen. In this study, 78% of OHSCDs occurred at home.
Although laparoscopic cholecystectomy (LC) is known to be safe in the treatment of acute cholecystitis (AC), the optimal timing of laparoscopic intervention remains controversial. The objective of this study is to prospectively compare the safety and cost effectiveness of early versus delayed LC in AC. Our study population consisted of 43 patients presenting with AC (localized tenderness, white blood cell count >10.0 or temperature >38.0° C, and ultrasound confirmation) who were prospectively randomized to early versus delayed LC during their first admission. Exclusion criteria included a history of peptic ulcer disease or evidence of gallbladder perforation. All patients were treated with bowel rest and antibiotics (piperacillin 2 g intravenous piggyback every 6 hours). Early treatment patients underwent LC as soon as the operating schedule allowed. Delayed treatment patients received anti-inflammatory medication (indomethacin 50 mg per rectum every 12 hours) in addition to bowel rest and antibiotics and underwent operation after resolution of symptoms or within 5 days if symptoms failed to resolve. Early LC was performed in 21 patients, whereas 22 patients underwent delayed LC. There was no difference in age, temperature, or white blood cell count on admission between groups. Early LC slightly reduced operative time and conversion rate. There was no difference in complications. Estimated blood loss was significantly lower in those receiving early LC. There was also a significant reduction in total hospital stay and hospital charges with early LC. We conclude that delay in operation combined with anti-inflammatory medication showed no advantage with regard to operative time, conversion, or complication rate. Furthermore, early laparoscopic intervention significantly reduced operative blood loss, hospital days, and hospital charges.
Background:
There is limited evidence for the use of postoperative antibiotics for simple appendicitis (SA) in children. Our aim was to conduct a prospective double-blinded randomized controlled trial to investigate this after a laparoscopic appendicectomy.
Methods:
Following ethical approval, children (≤16 years) undergoing appendicectomy were recruited at a single institution. Patients were randomized intraoperatively to receive either 2 postoperative intravenous doses of placebo or antibiotics (Abx). All patients received a dose of Abx at induction of anesthesia. Primary outcome was the incidence of postoperative wound infection (WI), and secondary outcome was the incidence of intra-abdominal abscess formation. Data are reported as number of cases (%), median (range), relative risk, and analyzed using Mann Whitney U test, Chi-square test, as appropriate, a P-value ≤0.05 was considered significant.
Results:
A total of 304 patients were randomized. Sixty-one were subsequently excluded due to protocol violations or recruitment errors; therefore, 243 were included in the final analysis. One hundred twenty-two patients received placebo and 121 Intravenous Abx. There was no difference between the sex (50F/72 M vs 47F/74 M, P = 0.8), median age (12.4 vs 12.2 years, P = 0.5), and postoperative length of stay in a hospital (27.2 vs 25.6 hours, P = 0.7). There was also no difference in the preoperative blood results. A total of 9 WIs occurred: 8/122 (6.6%) placebo versus 1/121 (0.8%) Abx, P = 0.01 [relative risk for WI 7.9 (95% confidence interval: 1.0–62.4)]. There were no intra-abdominal abscess in either groups.
Conclusions:
This prospective randomized double blinded randomized controlled trial has revealed a significant decrease in WI rates by giving 2 postoperative intravenous doses of Abx, suggesting postoperative Abx are of benefit in SA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
