prevention of adhesion using ringer lactate

Adhesions after abdomino-pelvic surgery are a cause of morbidity and reoperations. The use of human amniotic membrane (HAM) for adhesion prevention has given controversial results. The mode of administration of the amniotic membrane has not been well studied. This study assessed the efficacy of two modes of application of cryopreserved HAM, patch or fragmented in Lactated Ringer (LR) solution, for the prevention of pelvic adhesion formation postabdomino-pelvic surgery in a mice model. After a midline laparotomy incision, a small cautery lesion was done on each side of the abdominal wall peritoneum in mice...

INTRODUCTION: Subdural fluid collections following intraventricular and/or paraventricular procedures in pediatric neurosurgery are common and can be hard to treat. We describe our technique to close cortical defects by the aid of a fibrin adhesive and subsequent Ringer inflation with the aim to avoid cortical mantle collapse and to prevent the development of subdural fluid collections. MATERIALS AND METHODS: We report the preliminary results of a prospective study on a consecutive series of 29 children who underwent 37 transcortical or transcallosal surgical procedures since 2008 in our department...

OBJECTIVE: The objective of this multicenter, randomized study was to investigate the efficacy of the hydrophilic resorbable film PREVADH™ in preventing postoperative adhesions following myomectomy. STUDY DESIGN: Women scheduled for laparotomic myomectomy with intramural and/or subserous myomas of >60mm in diameter, and who wished to preserve fertility, were eligible. Patients were randomized immediately prior to abdominal wall closure to receive either hydrophilic resorbable film applied directly to the incisions (P-Group, n=33) or 500mL Ringer's lactate solution instilled into the pelvic cavity (R-Group, n=28)...

OBJECTIVE: To evaluate the efficacy of a crosslinked hyaluronic acid (HA) for the prevention of postsurgical adhesions after laparoscopic myomectomy using the Harmonic Ace. MATERIALS AND METHODS: Women 23-42 years of age who wished to conceive underwent laparoscopic myomectomy. As adhesion preventing agents, crosslinked HA gel was applied on the myometrial scar at the end of the surgery in Group A, whereas in Group B a Ringer's lactate solution was used in a prospective, observational study...

OBJECTIVE: Hypoxemic reperfusion attenuates brain injury secondary to severe cerebral ischemia, myocardial, and intestinal injury occurring in intestinal postischemic shock, and offers hemodynamic stabilization and attenuation of inflammatory response when applied in the resuscitation from hemorrhagic shock. In this study, we sought to investigate the effect of hypoxemic resuscitation on pulmonary endothelium. DESIGN: Prospective, randomized, controlled animal study...

BACKGROUND: Polyclonal anti-thymocyte globulins (ATGs) are immunosuppressive agents used for the treatment and prevention of acute organ rejection after transplantation. ATGs induce apoptosis and complement-mediated cell death in peripheral T-lymphocytes and have shown a reduction of leukocyte adhesion after ischemia-reperfusion (IRI). We analyzed the impact of different ATGs upon the expression of adhesion and inflammation molecules after IRI. MATERIALS AND METHODS: The major arteries and veins of the extremities of cynomolgus monkeys were surgically isolated and flushed with Ringer's lactate at 4 degrees C...

This study was conducted to determine the probability of adhesion formation with certain materials after abdominopelvic surgery, and to assess the effectiveness of adhesion-preventing agents. The study included 2 phases. In the first phase of the study, 50 rats that had been divided into 5 groups were examined. Group 1 served as the control group. In group 2, 2 mL blood was taken from the femoral vein of the rat; in group 3, 0.0625 g talcum powder was mixed with 2 mL saline; in group 4, 2 mL ileal content was identified; and in group 5, 2 mL cecal content had spilled into the peritoneum...

OBJECTIVE: To compare the effects of solid barriers (PDLA membrane and foil, Interceed), innovative barrier solutions (Adept and Hyalobarrier Gel, phospholipid emulsion), and Ringer's lactate solution in preventing postsurgical peritoneal adhesions in the rat. DESIGN: Prospective, randomized experimental study. SETTING: Rat model in an academic research environment. ANIMAL(S): Female, nonpregnant Wistar rats.

BACKGROUND/AIMS: This study was designed to evaluate the extent of adhesion formation to prostheses fixed with spiral tacks and to establish whether the use of Ringer's lactate or icodextrin could prevent these adhesions. METHODS: 24 New Zealand white rabbits weighing around 3,000 g were implanted with a 7 x 5 cm patch of ePTFE (DualMesh) through a midline laparotomy. The prosthesis was fixed to the intact peritoneum using spiral tacks. Three study groups were established according to whether the animals were: implanted with ePTFE fixed with spiral tacks or implanted with ePTFE fixed with spiral tacks and simultaneously administered Ringer's lactate or 4% icodextrin in the peritoneal cavity...

PURPOSE: To determine a way to prevent the formation of adhesions and delay the time of suture adjustment in the course of adjustable strabismus surgery, an animal study was performed to assess and compare the effects of mitomycin C (Mit-C) and viscoelastic material Viscoat (sodium hyaluronate 3% and chondroitin sulphate 4%, Alcon, Fort Worth, TX). METHODS: Right eyes of 47 rabbits were divided into three groups. After recession of the superior rectus muscle (SRM), Mit-C was administered beneath and over the SRM in Group M (16 eyes), Viscoat was administered beneath and over SRM in Group V (16 eyes), and ringer lactate was administered in Group C (15 eyes)...

According to a previous study, a pathologically increased intraabdominal pressure (IAP) reduces cardiac output (CO) and results in medium- to high-grade organ damage in a porcine model of the abdominal compartment syndrome (ACS). The purpose of this study was to evaluate whether fluid resuscitation can preserve organ integrity together with CO. We examined 12 domestic pigs with a mean body weight of 48 kg. We used a CO2 pneumoperitoneum to increase the IAP to 30 mmHg in 6 animals, and the others served as control group...

OBJECTIVE: To compare the antiadhesion efficacy of three agents (4% icodextrin, ferric hyaluronate gel, and Ringer's lactate) in severe peritoneal trauma caused by bipolar coagulation in a laparoscopic rat model. DESIGN: Prospective, randomized, blinded experimental study. SETTING: International Laparoscopic Surgery Centre, Clermont-Ferrand, France. ANIMAL(S): Female Sprague-Dawley rats. INTERVENTIONS: Animals were prospectively randomized to receive one of the three agents or to be controls...

OBJECTIVE: To assess whether polysaccharides isolated from fungi, Phellinus spp, could reduce the adhesion and abscess formation in a rat peritonitis model. SUMMARY BACKGROUND DATA: Although polysaccharides from Phellinus spp is a well-known material with antiinflammatory properties, little is known regarding its ability to prevent intraperitoneal adhesions. We have assessed the adhesion- and abscess-reducing effect of polysaccharides from Phellinus gilvus (PG) and Phellinus linteus (PL) in a rat peritonitis model...

AIM: To assess the adhesion- and abscess-reducing capacities of various concentrations of polysaccharides derived from fungus, Phellinus gilvus (PG) or Phellinus linteus (PL) in a rat peritonitis model. METHODS: In 96 SD rats, experimental peritonitis was induced using the cecal ligation and puncture model (CLP). Rats were randomly assigned to 8 groups; Ringer's lactate solution (RL group), hyaluronic acid (HA group), 0.025%, 0.25%, and 0.5% polysaccharides from PG (PG0...

Adhesion formation is of major concern to the pelvic surgeon. Most patients develop postoperative adhesions regardless of whether the mode of access to the abdominal cavity is by laparoscopy or laparotomy. Infertility is related to adhesions in the pelvis in 15-20% of cases. Peritoneal adhesions are the main cause of mechanical bowel obstruction in 65-80% of cases and contribute to a large extent to health-care expenditures. To prevent the formation of postoperative adhesions, a variety of medications have been studied such as glucocorticoids, heparin, dextran 70, saline solution, antibiotics, promethazine, antihistamines, prostaglandin synthesis inhibitors, Ringer's lactate solution, calcium-channel blockers and barriers such as Interseed and Gore-Tex...

SETTING: Departments of Obstetrics and Gynecology, university-affiliated and public hospitals, Rome, Italy. PARTICIPANTS: Members of the Roman Group of Gynecologic Endoscopy. INTERVENTION: Evaluation of forms returned. MEASUREMENTS AND MAIN RESULTS: The response rate to either electronic or regular mailing was 31%, for a total of 42 forms evaluated...

OBJECTIVE: Two controlled in vivo studies in rats have investigated the effect of icodextrin solution on intraperitoneal chemotherapy-induced adhesion formation. The first study evaluated the effect of three concentrations of icodextrin (4, 15, 20% w/v) in comparison to a phosphate-buffered saline (PBS) control in response to intraperitoneal doxorubicin (n = 40). The second study compared the effect of 4% icodextrin to Ringers' lactate solution (RLS) control in response to intraperitoneal bleomycin (n = 30)...

BACKGROUND: Polymorphonuclear neutrophil (PMN) sequestration in the lung is a hallmark of acute respiratory distress syndrome (ARDS). We have shown that 25% Albumin (A25) resuscitation attenuates lung injury after hemorrhagic shock and lipopolysaccharide (LPS) exposure by reducing lung leukosequestration. We hypothesize that this protective property is mediated by alteration of neutrophil-endothelial cell adhesive interactions. MATERIALS AND METHODS: A 2-hit rodent model of shock resuscitation was used...

Postoperative peritoneal adhesions impose a long-term risk of morbidity and mortality. Adjunctive means are needed to prevent these complications. In previous studies we could demonstrate the efficacy and safety of intraperitoneally applied phospholipids with regard to adhesion prevention and wound healing, respectively. The assumption is that phospholipids rapidly adhere to the peritoneal surface and to the mesothelial lesions. This study was designed to evaluate the influence of early drainage of the administered fluid volume on the control of adhesion formation...

BACKGROUND: Adhesion-related readmissions are frequent sequelae to gynaecological surgery. Attempts to prevent adhesions by separating healing peritoneal surfaces include site-specific barriers and hydroflotation by instilled solutions. Rapid absorption limits the effectiveness of solutions such as Ringer's lactated saline (RLS). This pilot study assessed the safety, tolerability and preliminary effectiveness of a non-viscous, iso-osmolar solution of 4% icodextrin, an alpha-1,4 glucose polymer with prolonged intraperitoneal residence, in reducing adhesions after laparoscopic gynaecological surgery...
