OBJECTIVETo investigate the influence of changes in perioperative antibiotic prophylaxis (PAP) duration in colorectal surgery on surgical site infection (SSI).

METHODSThe data on PAP in April and October between 2011 and 2013 was collected from tertiary and secondary hospitals in Shanghai. Prevalence of SSI rates over the same period was compared.

RESULTSA total of 2 465 cases of colorectal surgeries were studied over the three-year period, including 1 784 cases in tertiary hospitals and 681 cases in secondary hospitals. In 940 surgical operations, PAP duration were within 72 hours, accounting for 38.1% of all cases. 48.0% of the operations in 2013 had a PAP within 72 hours, which is significantly higher than that of 20.8% seen in 2011 (χ(2) = 129.986, P = 0.000). In 2013, 53.5% of the all procedures in tertiary hospitals had PAP ≤ 72 hours, compared with 35.5% in secondary hospitals over the same period (χ(2) = 22.714, P = 0.000). Combined uses of nitroimidazoles, with an effect of anti-anaerobic, were used much more commonly in tertiary (76.0%) than in secondary hospitals (41.4%) (χ(2) = 267.820, P = 0.000). The usage of cephamycin were higher in secondary (20.6%) than in tertiary hospitals (4.7%) (χ(2) = 149.865, P = 0.000). According to the investigations by SICC on prevalence of healthcare-associated infections between 2011 and 2013, colorectal surgeries have an average SSI rate of 2.0%. Stratified data showed that the rate of PAP ≤ 72 hours increase from 23.6% in 2011 to 45.8% in 2013 over the same period. However, the SSI rate did not show a significant change (1.9% in 2011, 1.7% in 2013). There was no linearly dependent between the two rates (r = 0.015, P = 0.990).

CONCLUSIONSThe proportion of rational PAP of colorectal surgeries in Shanghai has increased. Perioperative antibiotic prophylaxis duration decreased, while SSI rates over the same period did not increase.

PURPOSE: The average rate of surgical site infections (SSIs) for laparoscopic cholecystectomy (LC) has been reported in the literature to be between 0.4% and 6.3%. Also, these recent reviews have concluded that a prophylactic antibiotics for elective LCs in low-risk patients is not useful, but there were no results in high-risk patients. METHODS: The aim of this study was to investigate the role of a single dose of first-generation cephalosporin as a prophylactic antibiotic for patients undergoing elective LC, regardless of patient risk. This randomized clinical trial was conducted from October 2013 to December 2014 by single surgeon at our hospital. Patients were randomized into two groups by following method. Odd-numbered patients (group A) received 1-g cefazolin intravenously within 30 minutes before incision, whereas even-numbered patients (group B) received normal saline intravenously instead of prophylactic antibiotics, with the aim of including 100 patients in each group. SSIs were recorded and compared between the groups. RESULTS: There were no differences in preoperative demographics and postoperative findings between the groups. There were no superficial and deep SSIs in either group, 9 cases of superficial seromas developed (4.5%) in the cohort: 4 in group A (4%) and 5 in group B (5%). There were no significant associations between SSIs and the use of prophylactic antibiotics in either group. Additionally, the high-risk group did not show a significantly increased rate of SSIs. CONCLUSION: Based on our study, prophylactic antibiotics are not necessary in elective LC, regardless of patient risk.

Infection is the most common complication and the most common cause of death in burn patients. It is very important to employ anti-infection measures reasonably and effectively for victims of major burns. However, a consensus of opinion of how to use systemic antibiotics in prophylaxis of infection in the early stage of burn is still lacking. The indications of the early systemic use of prophylactic antibiotics are discussed in this article.

OBJECTIVETo investigate and analyze the perioperative prophylactic use of antimicrobial agents in 118 hospitals in China.

METHODS3557 medical records (from September to December, 2006) of 118 hospitals were drawn out randomly. The perioperative prophylactic use of antimicrobial agents was investigated and analyzed.

RESULTSProphylactic antimicrobial agents were used in 3485 cases (98%). The first 3 kinds of antimicrobial agents most in use were cephalosporins of 3rd generation (1775/3485, 50.4%), 2nd generation (1191/3485, 34.2%) and fluoroquinolones (1120/3485, 34.1%). The average durations of antibiotic use were 7.4 d for class I (clean) wounds 7.6 d for class II (clean/contaminated) wounds and 10. 5 d for class III (contaminated) wounds. Only 30.4% of patients received antibiotics within 2 h prior operation, and 52.2% of patients did not received antibiotics until the operation was completed. There were no indications for prophylactic antibiotic use in 16.7% of cases. Combining use of antimicrobial agents were performed in 56.5% of cases, and 22.1% of them lack of reasonable indications.

CONCLUSIONSInappropriate use of perioperative prophylactic antimicrobial agents is common and must be subjected to standardization.

OBJECTIVETo investigate the reasonable proposal of prophylactic antibiotics use in selective colorectal operation.

METHODSOne hundred and sixty-five patients underwent colorectal surgery were randomized to Treatment 1 (55 cases), Treatment 2 (50 cases) and Control (60 cases) group. The Treatment 1 group was given oral MgSO4 solution at the night before operation, and Cefradine 2.0 g (I.V.) during the induction of anesthesia, continued with tow times of intravenous Cefradine 2.0 g and 0.5% Metronidazole 100 ml at an interval of 12 hours in 24 hours after the operation. The Treatment 2 group was given the same treatment as Treatment 1, but the antibiotics would not be withdrawn until 3-5 d after operation. On the basis of the treatment of Treatment 2 group, the Control group was given oral antibiotics 2-3 days before operation. Postoperative complications including surgical site infection, stoma leakage, dysbacteriosis, and WBC, body temperature, days of hospitalization and antibiotic expenses in the three groups were observed and compared.

RESULTSThere was no significant differences in surgical site infection, stoma leakage, WBC counting and its change, body temperature and hospital stay among the three groups (P > 0.05). The incidence rate of dysbacteriosis in Control group was significantly higher than that in Treatment 1 group (P < 0.05). The antibiotic expenses in the Treatment 1 group was significantly lower than those of the other two groups (P < 0.05).

CONCLUSIONSProphylactic antibiotic use during the induction of anesthesia and 24 hours after operation was reasonable in selective colorectal operation, it can prevent the surgical site infection effectively with good social-economic effects and fewer side effects.

OBJECTIVETo study the clinical effects of perioperative treatment by integrated traditional Chinese and Western medicine on postoperative parameters of TURP.

METHODSFrom Jun. 2002 to Oct. 2006, 238 cases of TURP were performed in our hospital, of whom, 179 (Group A) were treated by integrated traditional Chinese and Western medicine, and the other 59 (Group B) by Western medicine. The postoperative parameters of the 2 groups were recorded and compared.

RESULTSPostoperative catheter indwelling, hospital stay, Q(max) 4 w after TURP and incidence of bacteriuria (> 5 d) showed no significant difference (P > 0.05), while the incidence rates of overactive bladder and urgent urinary incontinence, hematuria time, dysuria time, IPSS score and QOL score 4 w after TURP were statistically different between the 2 groups (P < 0.05).

CONCLUSIONFor TURP patients, perioperative treatment by integrated traditional Chinese and Western medicine can reduce postoperative complications, increase the success rate of surgery and improve QOL score.

BACKGROUNDA prior study showed significant antibiotic resistance to quinolone in our population. In this study we aimed to evaluate and compare the efficacy of a single versus a combined prophylactic antibiotic regimen before transrectal ultrasound-guided prostate biopsy (TRUGPB).

METHODSA prospective randomized study was conducted at a university hospital. Patients undergoing TRUGPB were randomized into an amoxicillin-clavulanate alone (1 mg; one dose before and two doses after biopsy) or an amoxicillin-clavulanate + ciprofloxacin group (250 mg; one dose before and two doses after biopsy). Patients were surveyed for infection symptoms by phone on days 3 and 30 after TRUGPB. We defined an infective complication as the occurrence of symptoms including fever, chills or rigor within 30 days after prostate biopsy, requiring medical treatment or hospitalization, aided by a territory-wide electronic medical record system.

RESULTSBetween November 2007 and July 2009, 367 patients were randomized to either amoxicillin-clavulanate alone or amoxicillin-clavulanate + ciprofloxacin group. The infection rates after TRUGPB were 3.91% in the former group (7 out of 179 patients) versus 0.53% (1 out of 188 patients) in the latter. Sixty-three percent (5/8) of patients with infective complications needed hospitalization. There was no intensive care unit admission or mortality during the study period.

CONCLUSIONSCombining prophylactic antibiotics with amoxicillin-clavulanate + ciprofloxacin significantly reduced the incidence of infective complications after TRUGPB. We recommended a combination regimen, especially in centre with high incidence of post-TRUGPB infection.

PURPOSE: Transrectal ultrasonography-guided prostate biopsy (TRUS-Bx) is an essential procedure for diagnosing prostate cancer. The American Urological Association (AUA) Guideline recommends fluoroquinolone alone for 1 day during TRUS-Bx. However, this recommendation may not be appropriate in regions where the prevalence of quinolone-resistant Escherichia coli is high. We investigated the real practice of antibiotic prophylaxis for TRUS-Bx in Korea. MATERIALS AND METHODS: A total of 77 hospitals performing TRUS-Bx were identified and an e-mail was sent to the Urology Department of those hospitals. The questions in the e-mail included the choice of antibiotics before and after the procedure and the duration of antibiotic therapy after TRUS-Bx. RESULTS: A total of 54 hospitals (70.0%) responded to the e-mail. Before TRUS-Bx, all hospitals administered intravenous antibiotic prophylaxis. The percentage of hospitals that used quinolone, cephalosporin, and aminoglycoside alone was 48.1%, 20.4%, and 9.3%, respectively. The percentage of hospitals that used two or more antibiotics was 22.2%. After biopsy, all 54 hospitals prescribed oral antibiotics. The percentage of hospitals that prescribed quinolone alone, cephalosporin alone, or a combination of two or more antibiotics was 77.8%, 20.4%, and 1.8%, respectively. The duration of antibiotic use was more than 3 days in most hospitals (79.6%). Only four hospitals (7.4%) followed the AUA recommendation of a 1-day regimen. CONCLUSIONS: The AUA recommendation was not followed by most hospitals in Korea. This clinical behavior might reflect the high quinolone resistance rate in Korea, and further studies on the most efficient prophylactic antibiotics after TRUS-Bx in Korea are warranted.

OBJECTIVES: The purpose of this study was to analyze the association between the pattern of prophylactic antibiotic use (PAU) and the surgical site infection (SSI) rate for major surgeries in Korea. METHODS: We retrospectively reviewed the medical records of patients who underwent cardiac, colon and gastric surgery, hysterectomies and hip/knee replacements at 20 hospitals, and inclusive of over 500 beds. We randomly sampled 60 cases per surgery type for patients discharged between September and November, 2006. A total fo 2,924 cases were included in our analysis. Cox's proportional hazard analysis was conducted to evaluate the association between the pattern of PAU and SSI rate. RESULTS: The proportion of patients who received their first prophylactic antibiotics (PA) 1 hour before incision was 65.5%, who received inappropriate PAs was 80.8%, and the proportion of patients whose PA was discontinued within 24 hours of surgery was 0.5%. The average duration of PAU after surgery was 9 days. The relative risk (RR) of SSI in patients who received their first PA more than 1 hour before incision was significantly higher than for those who received it within 1 hour prior to incision (RR=8.20, 95% CI=4.81-13.99). Inappropriate PA selection increased SSI rate, albeit with marginal significance (RR=1.97, 95% CI=0.96-4.03). Also, prolonged PAU following surgery had no effect on SSI rate. CONCLUSIONS: These results suggest that the pattern of PAU in the surgeries examined was not appropriate. Errors in the timing of PAU and of PA selection increase SSI rate. SSI rate remained unaltered following prolonged PAU after surgery.
