Role of peritoneal lavage in adhesion formation and survival rate in rats: an experimental study.

Following laparotomy, almost 95% of patients develop adhesions. To prevent adhesion formation, peritoneal lavage has been investigated and many different lavage solutions have been proposed. In this study, different peritoneal lavage solutions were evaluated, testing their ability to prevent adhesion formation. Three consecutive steps were followed: (1) The lethal dose of Eschericia coli injected in the rat peritoneal cavity was determined, (2) the morbidity and mortality rates of different solutions for peritoneal lavage (i.e., saline, twice-distilled water, antiseptics, and antibiotics solutions) was investigated, and (3) the capability of the different lavage solutions to prevent adhesion formation was tested. Two hundred and ninety-eight rats were employed in this study. After intraperitoneal injection of E. coli, infection (clinical signs and animal vitality), adhesion formation (explorative laparoscopy, peritoneumgraphy and Zühlke scale grading), and animal performance status were investigated. All differences were evaluated by chi-square and analysis of variance (ANOVA) tests. Saline solution showed a low morbidity rate with no deaths. Twice-distilled water was associated with 100% mortality rate, as opposed to 45-75% for antiseptics, and 0-3% mortality for antibiotics. Antibiotics determined higher adhesion formation by Zühlke score as compared to saline solution (p < .001), while no difference was observed between antiseptics and saline (p = NS). Peritoneal lavage with 37 degrees C saline solution was associated with low adhesion formation and high survival rate as compared to twice-distilled water and antiseptics. Antibiotics solutions had high survival rate and high adhesion formation. Twice-distilled water and antisepsis should be avoided when based on the data obtained in this work.

Effect of predelivery vaginal antisepsis on maternal and neonatal morbidity and mortality in Egypt.

OBJECTIVE: The objective of this study was to determine if cleansing the birth canal with an antiseptic solution at delivery reduces infections in mothers and their newborn babies. METHODS: Women giving birth in the University Hospital, Alexandria, and their newborns were studied. No intervention for 3 months was followed by 3 months of intervention. Intervention consisted of manually wiping the maternal birth canal with a 0.25% chlorhexidine solution at admission and at every vaginal examination before delivery. Babies were also wiped with chlorhexidine. RESULTS: The study enrolled 4415 women and 4431 newborns. The nonintervention phase comprised 2128 mothers and 2138 newborns, and 2287 mothers and 2293 babies were enrolled in the intervention phase. There were no adverse reactions related to the intervention among the mothers or their children. There was no difference in the overall number of neonatal admissions in both groups, but the admissions because of infection, deaths, and mortalities from infection were significantly less in the intervention group. Among mothers receiving the intervention, admissions, deaths, and infections were significantly reduced. CONCLUSIONS: Cleansing the birth canal with chlorhexidine reduced neonatal and maternal postpartum infections. The safety, simplicity, and low cost of the procedure suggest that it should be considered standard care for the reduction of infant and maternal morbidity and mortality.

Comparison of four antiseptic preparations for skin in the prevention of contamination of percutaneously drawn blood cultures: a randomized trial.

A number of skin antiseptics have been used to prevent the contamination of blood cultures, but the comparative efficacies of these agents have not been extensively evaluated. We therefore sought to compare the efficacy of four skin antiseptics in preventing blood culture contamination in a randomized, crossover, investigator-blinded study conducted in an emergency department and the inpatient wards of a university hospital. The patient group included all patients from whom blood samples were obtained percutaneously for culture. Skin antisepsis was performed with 10% povidone-iodine, 70% isopropyl alcohol, tincture of iodine, or povidone-iodine with 70% ethyl alcohol (i.e., Persist). The blood culture contamination rate associated with each antiseptic was then determined. A total of 333 (2.62%) of 12,692 blood cultures were contaminated during the study period compared to 413 (3.21%) of 12,859 blood cultures obtained during the previous 12-month period (relative risk = 0.82; 95% confidence interval, 0.71 to 0.94; P = 0.006). During the study, the contamination rates were determined to be 2.93% with povidone-iodine, 2.58% with tincture of iodine, 2.50% with isopropyl alcohol, and 2.46% with Persist (P = 0.62). We detected no significant differences in the blood culture contamination rates among these four antiseptics, although there was some evidence suggesting greater efficacy among the alcohol-containing antiseptics. Among the evaluated antiseptics, isopropyl alcohol may be the optimal antiseptic for use prior to obtaining blood for culture, given its convenience, low cost, and tolerability.

[Antiseptic resistance of clinical strains of Staphylococcus aureus].

To evaluate the activity of antiseptics and the sensitivity-resistance of bacteria to antiseptics, a number of characteristics has been used, including the minimum inhibiting concentration for different strains, the frequency of statistical and clinical resistance, the antiseptic activity index. A wide spread of S. aureus strains isolated from patients with hospital infections has been revealed. Differences in the resistance of bacterial strains have been established, depending on the type of the antiseptic and the ecovar of bacteria: among hospital ecovars, resistant strains occur more frequently and can resist a wider range of antibiotics. In staphylococcal hospital ecovars the occurrence and level of resistance to a number of widely used antiseptics increase with time. In connection with a wide spread of staphylococcal hospital strains resistant to antiseptics, measures on the control of the circulation of such strains should be introduced into hospitals, and the data thus obtained should be used for the periodic reevaluation of antiseptics used in medical practice and for the choice of preparations to be used for individual therapeutic and prophylactic antisepsis.

The role of iodine in antisepsis and wound management: a reappraisal.

For more than 150 years, iodine has been used for the prevention of infection and for the treatment of wounds. Nowadays a large amount of published evidence is available and, although it is generally in support of the use of iodine product, it is confused by being a mixture of laboratory, animals and human studies, often using different preparations. This makes interpretation and comparison difficult. After new developments and publications, the role of iodine in antisepsis and in wound management needs to be reevaluated. We mainly focused our review on the following problems: the role of the newly developed formulations of iodine preparations, its antimicrobial activity, the possibility of impairing the wound healing process, the role of iodine in the problem of growing resistance against antibiotics and antiseptics. New formulations seem to keep the same clinical efficacy, avoiding the problem of toxicity; it seems that the antibacterial activity of iodine is superior compared to other products and, in contrast with antibiotics and other antiseptics, it seems to have no resistance problem. It seems that povidone-iodine has all the characteristics to become the first choice antiseptic in wound treatment.
