The CO2- laser knife was used for partial nephrectomy in an experimental study of 20 mongrel cats. Of these, 16 survived, two died of peritonitis, and two died of unrelated causes. The inherent characteristics of precision and hemostasis of this modality, already found useful in controlling complications in other fields of surgery, proved to be a safe and effective method for partial nephrectomy as shown by angiography and histopathologic examinations of the operated kidneys at 0, 7, 14, 21, and 90 days after surgery. Complications such as hemorrhage or urinary fistula were nonexistent.

Our experience with 41 patients on CAPD is presented (127 patient months). Thirty-three patients were previously on intermittent peritoneal dialysis. We used 4 exchanges of 2 L each per 24 hours (8, 6, 6 and 4 hours dwell times). There was a dramatic fall in serum creatinine of 27%, BUN fell 22%, total CO2 rose 15%. Haemoglobin rose 10% and serum albumin fell by 5%. The incidence of peritonitis was one episode per 7.1 patient months. All patients noted an increase in well being. There were almost no dietary restrictions and patients gained real body weight. In most instances, their antihypertensive medication could be discontinued. This technique is superior to all the other forms of peritoneal dialysis.

The activity of cefuroxime, ciprofloxacin and imipenem against 50 coagulase-negative staphylococci (CNS) strains isolated from patients with peritonitis while on continuous ambulatory peritoneal dialysis (CAPD) was examined. Strains were cultured in both used peritoneal dialysis fluid (PUD) and broth (ISB) in an atmosphere of air with 5% CO2. MICs of cefuroxime, ciprofloxacin and imipenem differed significantly between the two media for 40%, 26% and 42% of strains, respectively. In three-quarters of these cases the MICs were higher in PUD compared to ISB. The ability of each antibiotic to kill six strains of CNS adherent to silicone rubber was also examined. Once again, differences in killing were noted between the two media. At least two-thirds of the strains remained viable in the presence of concentrations of antibiotic equal to the MBC of each antibiotic and at least one-third survived antibiotic concentrations equivalent to those attained during treatment. Assessment of activity in PUD may provide a more realistic test for antibiotics to be used in the treatment of CAPD peritonitis.

Coagulase-negative staphylococci obtained from patients with continuous ambulatory peritoneal dialysis-related peritonitis were cultured in nutrient broth in an atmosphere of air containing 5% carbon dioxide (reflecting the CO2 tension found in freshly used dialysate). Significant differences were observed between the surface chemistries of cells grown in the two atmospheres, as determined by X-ray photoelectron spectroscopy and changes in the cell wall protein profile. The growth atmosphere also influenced the adherence potential toward polystyrene and silicone in a proportion of strains examined. Thus, gaseous conditions can profoundly influence the nature of the staphylococcal surface, and this should be considered in any in vitro study of in vivo behavior.

Used peritoneal dialysis fluid was collected from patients undergoing continuous ambulatory peritoneal dialysis, and its pH and composition were assessed after incubation in either air or air with 5% CO2. Precipitation of calcium, magnesium, phosphate, and proteins occurred in the dialysis fluid incubated in air at 37 degrees C and was associated with a mean pH increase of 1.23 U. Incubation of dialysis fluid in air with 5% CO2 prevented precipitation and maintained pCO2 and pH levels at those found physiologically. Coagulase-negative staphylococcal strains isolated from patients with peritonitis tended to grow less well in dialysis fluid incubated in air than in dialysis fluid incubated in the carbon dioxide-enriched atmosphere. MICs of cefuroxime, ciprofloxacin, and vancomycin for seven strains of coagulase-negative staphylococci in dialysis fluid were markedly affected by atmosphere type (16 of 21 MICs). Of these 16 atmosphere-dependent MICs, 14 were at least fourfold higher in air than in air with 5% CO2.

Twelve patients who had been on intermittent peritoneal dialysis (IPD) for an average of 18.3 months each, were switched to continuous ambulatory peritoneal dialysis (CAPD). CAPD experience is now 118 patient months (average 9.8 months per patient), and ten patients remain on CAPD. Serum chemistries reflected the change to continuous dialysis with a fall in serum creatinine, potassium, uric acid, phosphate, and BUN. The total CO2 rose markedly, indicating prevention of the recurrent metabolic acidosis experienced in IPD. Serum phosphate fell significantly into the normal range. Serum calcium rose slightly in six patients and significantly in three others. Serum alkaline phosphatase activity rose in seven patients, without development of clinical evidence of bone disease. Mean hematocrit values were higher in most patients of CAPD, but fell again after one year. The transient nature of the rise in hematocrit suggests that improved volume control, as reflected in blood pressure changes, may play a role in the frequently reported increase in hematocrit on CAPD. Despite an increase in peritonitis rate (one infection per 5.9 patient months on CAPD, versus one per 12.2 patient months on IPD), CAPD offers several distinct advantages over IPD, especially in control of uremic acidosis, phosphate retention, blood pressure and fluid management, as well as an overall improvement in physical and psychosocial well-being.

Earlier observations had indicated profound increases in the carbon dioxide tension of the myocardium, gastric wall, liver parenchyma, and renal cortex in the setting of extreme low-flow states of cardiac arrest and resuscitation, hemorrhagic shock, and anaphylactic shock. In venous blood draining the intestines, kidneys, and pelvic viscera, significant increases in PCO2 have also been observed during septic shock. In the present study, we investigated hepatic, renal, and cerebral cortical tissue carbon dioxide tension during intra-abdominal sepsis and shock in Sprague-Dawley rats. Peritonitis was induced by cecal ligation and fecal spillage. Over an interval of 320 +/- 60 minutes, we measured progressive reduction in mean aortic pressure from 152 +/- 11 mm Hg to 25 +/- 8 mm Hg and a decline in cardiac index from 492 +/- 75 ml/kg/min to 169 +/- 57 ml/kg/min. These hemodynamic deficits were accompanied by increases in liver tissue PCO2, from 58 +/- 4 mm Hg to 110 +/- 27 mm Hg (p = 0.006), in renal tissue PCO2, from 38 +/- 7 mm Hg to 115 +/- 24 mm Hg (p < 0.001), and in cerebral cortical tissue CO2, from 59 +/- 6 mm Hg to 108 +/- 16 mm Hg (p = 0.001). Arterial blood lactate content increased from 0.8 to 5.26 +/- 0.2 mmol/L (p = 0.001). Increases in blood lactate content preceded the changes in tissue PCO2 in each of these organs. These studies demonstrate that tissue hypercarbia is a more general phenomenon of low flow states, including that of circulatory shock associated with septic peritonitis.

A review of anaesthesia for gynaecologic laparoscopic surgery is given. Special criteria are needed for selection of patients, choice of anaesthesia and intraoperative monitoring. The cardiovascular and respiratory system are affected by tension from the pneumoperitoneum, absorption of CO2 and Trendelenburg position. Gas insufflation can provoke venous gas embolism, pneumothorax, pneumomediastinum, pneumopericardium and subcutaneous emphysema. The introduction of laparoscopic instruments may result in unintentional injuries to intra-abdominal organs. The possibility that the procedure may have to be converted to open laparotomy needs to be considered. Bowel burns may result in perforation, peritonitis and sepsis. Laparoscopy is contraindicated in patients with serious cardiac disease, extensive bowel adhesions or intestinal obstruction. General anaesthesia with muscle paralysis, tracheal intubation and controlled ventilation is the preferred technique in these cases. Short acting anaesthetics are preferred in day case laparoscopy. Central neural blockade or infiltration anaesthesia supplemented with sedation and analgetics can be used for short laparoscopic procedures. The electrocardiogram, noninvasive arterial pressure monitor, airway pressure monitor, intra-abdominal pressure monitor, pulse oximeter and CO2 monitor are used routinely. Antiemetics and analgetics may be needed postoperatively.

Laparoscopic surgical repair of perforated gastroduodenal ulcer is technically feasible. To study the effect of a pneumoperitoneum on the extent and severity of peritonitis this animal study was devised. In rats gastric ulceration was induced by instillation of ethanol (50%, 2 ml) and followed by gastrotomy to simulate perforation. Animals were randomly allocated to pneumoperitoneum (PP) and control groups. In PP groups CO2 was insufflated intraperitoneally 6, 9, 12, and 24 h after gastrotomy. In controls the abdomen was only punctured. Animals were sacrificed 5 h after the end of PP or abdominal puncture. Blood cultures and intraabdominal swabs were assessed. A peritonitis severity score (PSS) based on histologies from peritoneum, liver, left kidney, spleen, and first jejunal loop was estimated. Six and 9 h after gastrotomy no significant differences between the PP and control groups were observed; 12 h after gastrotomy cultures of blood samples and abdominal swabs were positive in 67% and 75% in the PP group compared to 42% (P < 0.05), and 42% (P < 0.05) in controls. The mean PSS was 20.8 (standard deviation [SD] 2.2) in the PP group compared to 11.3 (1.5) (P < 0.01) in controls; 24 h after gastrotomy cultures of blood samples and abdominal swabs were positive in 83% and 100% in the PP group compared to 42% (P < 0.05) and 50% (P < 0.01) in controls. The mean PSS was 22.1 (1.5) in the PP group compared to 11.8 (2.4) (P < 0.01) in the controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Two different fluid solutions were infused through percutaneous cecal catheters in 6 healthy ponies to determine the effects on body weight; CBC; packed cell volume (PCV); total plasma protein concentration; plasma fibrinogen concentration; abdominal fluid analysis; concentrations of blood urea nitrogen (BUN), serum creatinine, Ca, total CO2 (TCO2), Na, Cl, K, and P; and fractional clearance (FC) of Na, Cl, K, and P. During intracecal administration of solution 1, FCNa and FCCl were significantly increased, whereas FCK and BUN were significantly decreased. During administration of solution 2, FCNa and serum P were significantly increased, while PCV was significantly decreased. All ponies developed peritonitis during the study. Complications included catheter-related problems, diarrhea, laminitis, and hypocalcemia. We concluded that hydration and electrolyte balance could be maintained by administration of crystalloid solutions intracecally, but that complications were associated with the procedure.
