Microbiological examination of bandage soft contact lenses used in laser refractive surgery.
BACKGROUND: Disposable soft contact lenses are known to be colonized by bacteria and play a key role in bacterial keratitis pathogenesis. Such lenses, commonly used after laser refractive surgery procedures in which postoperative corneal infiltrations are sometimes observed, are potentially a substrate for bacterial inoculation. This study evaluates the extent of such a contamination. METHODS: Sixty disposable lenses collected from 60 eyes of patients who underwent photorefractive keratectomy (PRK), photoastigmatic refractive keratectomy (PARK), or laser in situ keratomileusis (LASIK) for the treatment of myopia or hyperopia were collected under sterile conditions over 4 months and cultured in various media. Results were statistically analyzed and the correlation with clinical and epidemiological data was examined. RESULTS: Eleven (18.3%) of the examined lenses were contaminated with Staphylococcus epidermidis. No other bacteria or fungi were found. Contamination was significantly more common among female patients (P = .036). Correlation with the other clinical or operative parameters examined was statistically insignificant. CONCLUSIONS: Contamination was independent of the surgical procedure and females who were frequent users of eyelid cosmetics displayed higher contamination frequencies, suggesting that bacteria possibly originate from eyelid flora. The isolation of Staphylococcus epidermidis requires close postoperative surveillance, since it is a known cause of keratitis. Prophylactic postoperative treatment with tobramycin, gentamycin, or sulphonamides could be indicated.

Antibiotic administration in patients undergoing common surgical procedures in a community teaching hospital: the chaos continues.
The influence of recently published guidelines by the Surgical Infection Society (SIS) on current surgical practice are not well documented. The appropriateness of antibiotic administration in a cohort of surgical patients undergoing elective and emergency surgery in a department of surgery in an urban, community-based, private, 560-bed teaching hospital was retrospectively reviewed. The following were the criteria defining administration as appropriate as modified from SIS guidelines: Prophylactic use: (1) started prior to operation; (2) spectrum appropriate to the specific operation; (3) duration </= 24 hours. Therapeutic use: (1) started prior to operation; (2) spectrum appropriate to pathology; (3) Duration </= 24 hours for contamination or "resectable" infection and </= 5 days for established infection in the absence of clinical evidence of persisting infection. Any switchover from an appropriate agent to another appropriate or inappropriate agent in the same patient in the absence of microbiologic or clinical indication was considered inappropriate administration. We reviewed the charts of 211 randomly selected patients who underwent elective (n = 132) or emergency (n = 79) procedures during 1996. The operations included gastrectomy (n = 22), appendectomy (n = 27), open (n = 5) or laparoscopic (n = 27) cholecystectomy, colectomy (n = 28), hysterectomy (n = 8), laparotomy for intestinal obstruction (n = 11), mastectomy (n = 26), and ventral hernia repair (n = 37). A total of 17 antibiotics were used for prophylaxis and 21 for therapy. In 156 patients (74%) the administration was considered inappropriate. Eight patients in the inappropriate group developed diarrhea (two cases of Clostridium difficile-induced colitis) compared to two cases of diarrhea in the appropriate group (nonsignificant). The average duration of administration after elective and emergency operations was 3.3 and 5. 7 days, respectively. The total expense for excessive duration of administration was $18,533. Many surgeons are not familiar with the spectrum of antimicrobials and often do not distinguish between prophylactic and therapeutic administration. Antibiotic usage in current surgical practice is often inappropriate, excessive, and chaotic.

ACOG Practice Bulletin No. 74. Antibiotic prophylaxis for gynecologic procedures.
Surgical site inflection remains the most common surgical complication. Up to 5% of operative patients will develop a surgical site infection leading to a longer hospital stay and increased cost. One of the advances in infection control practices has been the selective use of antibiotic prophylaxis. However,antibiotic use, especially prophylactic antibiotic use, has been associated with the selection of antibiotic-resistant bacteria. Indiscriminate use of prophylactic antibiotics for institutions as well as for individual patients promotes this dangerous side eject. There are acknowledged consequences of prophylactic antibiotic use for institutions as well as for individual patients. It is important for clinicians to understand when antibiotic prophylaxis is indicated and when it is inappropriate. The purpose of this document is to review the evidence for surgical site infection prevention and appropriate antibiotic prophylaxis for gynecologic procedures.

Prophylaxis for intraabdominal surgery.
Great progress has been made in the last decade concerning the appropriate use of antibiotic prophylaxis in the patient undergoing abdominal surgery. Well-controlled, prospective, blind studies have outlined many of the areas in which antibiotic prophylaxis is of benefit as well as those clinical settings in which the risks of antibiotic prophylaxis outweigh the expected value. Historically, the most common errors in usage included the widespread use of antibiotic prophylaxis in clean surgical procedures as well as the faulty timing of initial administration. Currently, the most common error is the practice of continuing the administration of the antibiotic agents beyond the time necessary for maximal benefit (greater than 72 hr). In order to administer prophylactic antibiotics appropriately in the various clinical settings on the surgical service in which this practice has been of proven value, one must be aware of the following nuances: (1) the choice of the antibiotic agent should be based on the type of organisms usually causing infection; (2) the route of administration must be appropriate; (3) the dosage necessary to attain efficacious levels of antibiotic in tissue or serum must be appropriate; and (4) the timing of administration should offer the maximal benefits without risk of the adverse effects.

Treatment of meralgia paresthetica with a deep inferior epigastric perforator adiposal flap: case report.
A case of a 40-year-old female with meralgia paresthetica after malignant tumor resection in the right inguinal region is reported. Traditionally, meralgia paresthetica is treated with neurotransection or neurolysis. The therapeutic strategy using neurolysis, and the use of a deep inferior epigastric perforator adiposal flap wrapping as a prophylactic procedure against reentrapment is discussed.

Double breasting technique for residual cavity in hepatic hydatid.
Nine patients with univescicular echinococcal cysts in the liver were subjected to operative removal followed by a novel technique of obliteration of the residual space in the liver. The simple double breasting procedure was not associated with any complications and there was a considerable reduction in the median operating time (2 h 15 min) as well in median hospital stay (5 days). There was no recurrence with a median follow-up of 2 years and 4 months. None of the patients received albendazole either prophylactically or post-operatively.

[A multi-center prospective study for antibiotic prophylaxis to prevent perioperative infections in urologic surgery].
In order to assess the ability of our protocol for antibiotic prophylaxis to prevent perioperative infections in urologic surgery, 1,353 operations of open and laparoscopic urologic surgery conducted in 21 hospitals between September 2002 and August 2003 were subjected to analyses. We classified surgical procedures into four categories by invasiveness and contamination levels: Category A; clean less invasive surgery, Category B; clean invasive or clean-contaminated surgery, Category C; surgery with urinary tract diversion using the intestine. Prophylactic antibiotics were administrated intravenously according to our protocol, such as Category A; first or second generation cephems or penicillins on the operative day only, Category B; first and second generation cephems or penicillins for 3 days, and Category C; first, second or third generation cephems or penicillins for 4 days. The wound conditions and general conditions were evaluated in terms of the surgical site infection (SSI) as well as remote infection (RI) up to postoperative day (POD) 30. The SSI rate highest (23.3%) for surgery with intestinal urinary diversion, followed by 10.0% for surgery for lower urinary tract, 8.9% for nephroureterctomy, and 6.0% for radical prostatectomy. The SSI rates in clean surgery including open and laparoscopic nephrectomy/adrenalectomy were 0.7 and 1.4%, respectively. In SSIs, gram-positive cocci such as methicillin-resistant Staphylococcus aureus (58.8%) or Enterobacter faecalis (26.5%) were the most common pathogen. Similarly, the RI rate was the highest (35.2%) for surgery using intestinal urinary diversion, followed by 16.7% for surgery for lower urinary tract, 11.4% for nephroureterctomy, and 7.6% for radical prostatectomy, while RI rates for clean surgery were less than 5%. RIs most frequently reported were urinary tract infections (2.6%) where Pseudomonas aeruginosa (20.3%) and Enterobacter faecalis (15.3%) were the major causative microorganisms. Parameters such as age, obesity, nutritional status (low proteinemia), diabetes mellitus, lung disease, duration of operation, and blood loss volume were recognized as risk factors for SSI or RI in several operative procedures. Postoperative body temperatures, peripheral white blood counts, C reactive protein (CRP) levels in POD 3 were much higher than those in POD 2 in cases suffering from perioperative infections, especially suggesting that CRP could be a predictable marker for perioperative infections.

Patterns and prognosis of Clostridium difficile colitis.
UNLABELLED: The incidence of Clostridium difficile colitis has increased during recent years, presumably because of liberal use of broad-spectrum antibiotic regimens. METHODS: A retrospective review to determine patterns of C. difficile colitis development, morbidity, and treatment results was undertaken. During an 18-month period, 90 patients were diagnosed with C. difficile colitis by fecal toxin assays. Patient demographics, symptoms, previously administered antibiotic regimens, diagnostic evaluations, treatment modalities, morbidity, and mortality were identified, entered into a computer data base, and analyzed. RESULTS: The mean age was 58 years; males outnumbered females 1.2:1. Among 90 patients, 41 (46 percent) developed C. difficile colitis after surgical procedures. Eighty (89 percent) patients received antibiotic therapy before developing C. difficile colitis: 35 (44 percent) for documented infections and 45 (56 percent) as empiric or prophylactic therapy. Cephalosporins, penicillins, quinolones, vancomycin, and aminoglycosides were the most frequently administered antibiotic classes prior to C. difficile colitis diagnosis. Ten (11 percent) patients developed C. difficile colitis without previous antibiotic therapy. Eighty-two (91 percent) patients presented with diarrhea, while eight (9 percent) had fever only. Primary C. difficile colitis treatment for both groups included vancomycin (66 percent), metronidazole (24 percent), or both drugs (10 percent). Ten (11 percent) patients received no treatment. No patient developed toxic colitis or megacolon. Colonoscopy was performed in four (4 percent) patients; pseudomembranes were identified in one (25 percent) patient. There was one C. difficile colitis recurrence after treatment, but no C. difficile colitis-associated morbidity. Mortality (14 patients, 16 percent) was not related to C. difficile colitis, but to underlying illness. No difference in patient age, sex, previous antibiotic administration, serum albumin, total days hospitalized, duration of C. difficile colitis antibiotic therapy, C. difficile colitis treatment regimens, or mortality was identified between nonsurgical and surgical patients. The white blood cell count was significantly lower in the nonsurgical group however. Clostridium difficile colitis developed most commonly after antibiotic administration with symptoms of diarrhea, but did occur without previous antibiotic administration or diarrhea. CONCLUSION: Despite the clinical setting, C. difficile colitis had no associated morbidity and treatment was highly effective. Mortality was related to underlying medical illness, not C. difficile colitis.

Scarring following herpes simplex infection of postsurgical cutaneous sites.
Herpes simplex type 1 produces a perilabial vesicular eruption that normally resolves without scarring. Three cases of herpetic infection associated with different dermatologic surgical procedures are presented. Those procedures involving reduction of cutaneous macrovascular blood supply via undermining or flap creation were followed by clinical scarring. None of the recognized etiologies of tissue compromise (bacterial infection, tension, host vascular disease, excessive inflammation, or edema) could be identified. It is speculated that in the immunocompetent host, small vessel injury secondary to herpes simplex may eventuate in scarring if the subdermal vascular network is significantly compromised. Prophylactic oral acyclovir may be useful in select instances where tissue blood supply is judged clinically tenuous and the frequency of herpetic infection at the surgical site judged worrisome.

[Clinical pathway "laparoscopic prostatectomy". Analysis of anesthesiological procedures in a randomized study].
METHODS: In this study we investigated the anesthesiological module of a clinical pathway. We chose the pathway of "laparoscopic prostatectomy" as an example for time-consuming minimally invasive surgery and 40 patients were randomly assigned to 2 groups receiving either total intravenous anesthesia (TIVA) using propofol/ remifentanil or balanced minimal flow anesthesia using desflurane/ remifentanil. During this module the indicators of quality such as vigilance, pain, postoperative nausea and vomiting (PONV) and mobilization were measured. Costs were evaluated and analyzed by a bottom-up procedure. RESULTS: There were no anesthesia-related deviations from clinical pathways and both forms of anesthesia management were equally well tolerated by the patients. No significant difference was observed regarding hemodynamic measurements or PONV. The patients in the desflurane/ remifentanil group recovered more rapidly (p=0.037) and had more pain. The amount of analgesic agents given immediately following anesthesia was significantly higher than in the TIVA group (p=0.017). The median anesthesia costs per minute for laparoscopic prostatectomy in the propofol group were 2.79 EUR (minimum cost 2.41 EUR, maximum cost 3.21 EUR) and in the desflurane group 2.68 EUR (minimum cost 2.45 EUR, maximum cost 3.39 EUR). The total anesthesia costs for both groups were within the proceeds matrix range for diagnosis-related groups (DRG). However, the cost analysis for medication was slightly higher than the proceeds matrix range for DRGs. CONCLUSION: Both forms of anesthesia can be implemented for time-consuming surgical procedures and allow a cost-effective anesthesia management. Anesthesiological procedures must go hand-in-hand with the type of anesthesia selected. The prophylactic use of analgetics for desflurane/ remifentanil anesthesia should be given earlier and in higher doses than in propofol/ remifentanil anesthesia. The prophylactic use of antiemetics following laparoscopic procedures of long duration is indicated. Optimizing anesthesiological procedures could lead to a continuous improvement in the quality of therapeutic pathways.

Vascular complications of osteochondromas.
PURPOSE: Osteochondromas are the most common benign tumor of the bone. They are sometimes responsible for vascular complications involving either veins or arteries, principally around the knee. METHODS: We report six cases of such complications. An extensive review of literature through a computerized research was performed. RESULTS: We found 97 cases that were previously reported in the English literature giving sufficient details and providing data on 103 cases for analysis. CONCLUSION: Surgical treatment of vascular complications of osteochondromas is recommended as an urgent procedure to avoid irreversible damages, such as arterial occlusion, embolism, or phlebitis. Prophylactic resection of osteochondromas in the vicinity of a vessel must be performed.

Principles of anti-infective therapy.
Antimicrobial drugs, along with competent surgical procedures, provide an effective means for restoration of oral health. In dentistry, antibiotics are indicated for either treatment of acute infections or for prophylactic coverage of patients at risk for developing bacterial endocarditis or other infections as the result of bacteremia caused by dental procedures. Whenever possible, a bactericidal agent is preferred because of greater effectiveness and less reliance on host defense mechanisms. For maximal effectiveness of antibiotic therapy of orodental infections, several factors must be evaluated in choosing an antibiotic: (1) antibacterial spectrum and specificity of the agent; (2) degree of bacterial resistance reported for the antibiotic; (3) concentrations achieved at various sites; (4) age, type, and extent of infection; and (5) various host factors.

The current treatment of oesophageal varices.
The wide range of management options available today are evaluated in this article. The advised management policy for acute variceal bleeding includes admission to a hospital with an interest in portal hypertension, resuscitation, the possible use of pharmacological agents to lower portal pressure, and definitive endoscopic therapy (either sclerotherapy or banding). More major surgical procedures (i.e. shunts or transection operations or TIPS) should be reserved for patients in whom endoscopic therapy falls. Long-term management to prevent recurrent variceal bleeding is somewhat more controversial. The options for the majority of patients are pharmacological therapy with beta-blockers, or repeated endoscopic therapy to eradicate varices, or a major surgical procedure, preferably a partial shunt. All patients should be considered for liver transplantation although few will ultimately end up as liver transplant candidates. Prophylactic therapy prior to a variceal bleed, other than beta-blockade in selected patients, is unjustified today because of the difficulty in identifying high-risk patients.

Antibiotic prophylaxis in biliary surgery.
Early studies in which a higher incidence of wound infection and septic complications in biliary surgery was found demonstrated the need for antibiotic prophylaxis. In two studies, one retrospective and one prospective, the role of prophylactic antibiotics in biliary surgery was studied in "at risk" and "no risk" groups of patients. Twenty-eight percent of "no risk" patients had a positive bile culture. It was concluded that a single dose of 1 g cefotaxime, administered upon induction of anaesthesia, is a safe and effective prophylactic regimen in biliary surgery.

Cost-effectiveness analysis of antiemetic therapy for ambulatory surgery.
STUDY OBJECTIVE: To compare the relative cost-effectiveness ratios of (1) therapy with ondansetron, droperidol, and metoclopramide in the prevention of postoperative nausea and vomiting (PONV), and (2) prophylactic versus rescue therapy of PONV with these agents. DESIGN: Cost-effectiveness analysis based on the estimated costs of 12 mutually exclusive outcomes identified by decision analysis. SETTING: Computer model of outcome established using data extracted from published studies and a survey of current practice in two university-affiliated hospitals. PATIENTS: Patients undergoing operations associated with a high risk of PONV. INTERVENTIONS: The cost-effectiveness of prophylactic antiemetic therapy was compared among three drugs and also compared with limiting treatment to established PONV. MEASUREMENTS AND MAIN RESULTS: Direct costs included drug acquisition, drug delivery, equipment used in managing vomiting, and additional nursing time costs. Indirect costs included drugs and materials used to treat persistent nausea and/or vomiting and the side effects of prophylactic drugs, increased time spent in the postanesthesia care unit, unanticipated hospitalization, and lost earnings due to hospitalization. Separate models were created for patients with both nausea and vomiting and with isolated nausea. The total incremental costs associated with the prophylactic use of ondansetron, metoclopramide, and droperidol were $37.74, $28.43, and $18.17 per patient, respectively. The costs per emesis-free patient with the prophylactic use of ondansetron, metoclopramide, and droperidol, were $55.91, $71.08, and $30.15, respectively, and per nausea-free patient $68.93, $82.74, and $33.52, respectively. Prophylactic antiemetic therapy was cost-effective for operations with a high frequency of emesis, whereas treatment of established symptoms was more cost-effective when the frequency was lower. For ondansetron, prophylactic use was cost-effective only when the frequency of emesis exceeded 33%, whereas prophylactic droperidol was cost-effective even if the frequency was 10%. CONCLUSIONS: When drug costs, efficacy, and adverse events were all considered, prophylactic droperidol was more cost-effective than ondansetron, and both drugs were more cost-effective than metoclopramide. However, the expected frequency of PONV, as well as local drug acquisition costs, can significantly influence whether a particular antiemetic is cost-effective when given prophylactically or only as therapy for established PONV.

Postoperative pain in ambulatory surgery.
UNLABELLED: Postoperative pain is a common reason for the delayed discharge and unanticipated hospital admission of out-patients. In this study, we examined the pattern of pain in ambulatory surgical patients and determined those factors that predict postoperative pain. Ten thousand eight consecutive ambulatory surgical patients were prospectively studied. Preoperative patient characteristics, intraoperative variables, and pain in the postanesthesia care unit (PACU) and the ambulatory surgical unit (ASU) and 24 h postoperatively were documented. The incidence of severe pain was 5.3% in the PACU, 1.7% in the ASU, and 5.3% 24 h postoperatively. In the PACU, younger male adults (36 +/- 13 vs 47 +/- 22 yr), ASA physical status I patients, and patients with a higher body mass index (26 +/- 5 vs 25 +/- 5 kg) had a higher incidence of severe pain. In the group with severe pain, the duration of anesthesia, the duration of stay in the PACU and the ASU, and the time to discharge was longer than in the group without severe pain. In the PACU, orthopedic patients had the highest incidence of pain (16.1%), followed by urologic (13.4%), general surgery (11.5%), and plastic surgery (10.0%) patients. In patients who had general anesthesia, the intraoperative dose of fentanyl was significantly smaller in the group with severe pain than in the group without severe pain when body mass index and duration of anesthesia were taken into consideration. Body mass index, duration of anesthesia, and certain types of surgery were significant predictors of severe pain in the PACU. This knowledge will allow us to identify those patients at risk of severe postoperative pain and manage them prophylactically. IMPLICATIONS: The pattern of pain was examined in 10,008 consecutive ambulatory surgical patients. The incidence of severe pain was 5.3% in the postanesthesia care unit, 1.7% in the ambulatory surgical unit, and 5.3% 24 h postoperatively. Body mass, duration of anesthesia, and certain types of surgery were significant predictors of pain in the postanesthesia care unit. These data will allow us to better predict those patients who need intense prophylactic analgesic therapy.
