The Misgav Ladach method for cesarean section compared to the Pfannenstiel method.

OBJECTIVE: The aim of the study was to evaluate the outcome of two different methods of cesarean section (CS). DESIGN: The study was designed as a prospective, randomized, controlled trial. SETTING: All CS were performed at the University Hospital in Uppsala, Sweden. POPULATION: Fifty women admitted to hospital for a first elective CS were consecutively included in the study. They were randomly allocated to two groups. METHODS: One group was operated on by the Misgav Ladach method for CS and the other group by the Pfannenstiel method. All operations were performed by the same surgeon. MAIN OUTCOME MEASURES: Duration of operation, amount of bleeding, analgesics required, scar appearance and length of hospitalization. RESULTS: Operating time was significantly different between the two methods, with an average of 12.5 minutes with the Misgav Ladach method and 26 minutes with the Pfannenstiel method (p<0.001). The amount of blood loss differed significantly, with 448 ml and 608 ml respectively (p=0.017). Significantly less analgesic injections and tablets (p=0.004) were needed after the Misgav Ladach method. CONCLUSION: The Misgav Ladach method of CS has advantages over the Pfannenstiel method by being significantly quicker to perform, with a reduced amount of bleeding and diminished postoperative pain. The women were satisfied with the appearance of their scars. In this study no negative effects of the new operation technique were discovered.

Review of the methods of the US Environmental Protection Agency for bromate determination and validation of method 317.0 for disinfection by-product anions and low-level bromate.

In recent years several methods have been published by the United States Environmental Protection Agency (EPA) which specify bromate as a target analyte. The first of these was EPA Method 300.0. As technological improvements in ion chromatographic hardware have evolved and new detection techniques have been designed, method detection limits for bromate have been reduced and additional procedures have been written, including EPA Method 300.1, 321.8 and, most recently, EPA Method 317.0. An overview of the evolution of these bromate methods since 1989 is presented. The focus is specific to each of these respective procedures, highlighting method strengths, weaknesses, and addressing how these methods fit into EPA's regulatory agenda. In addition, performance data are presented detailing the joint EPA/American Society for Testing and Materials multilaboratory validation of EPA Method 317.0 for disinfection by-product anions and low-level bromate.

A rebreathing method for measuring carbon monoxide diffusing capacity. A supplement to the single-breath method.

A rebreathing method for measuring carbon monoxide diffusing capacity is described. The method can be used in patients whose vital capacity is too small, or whose cooperation is inadequate, for the single-breath method. The apparatus is simple and the same gas mixtures are used as for the single-breath method. The results obtained by the rebreathing method are similar to those by the single-breath method (80% of the results by the rebreathing method lie within 20% of the value by the single-breath method). The rebreathing method also provides a measurement of the functional residual capacity.

Methods for measuring GFR with technetium-99m-DTPA: an analysis of several common methods.

Several commonly used scintigraphic methods of GFR measurement were evaluated. Forty-three adult patients with a wide range of ages and renal function were studied. The two-sample plasma method of Russell and the urinary method of Jackson were the most accurate methods overall. The one-sample plasma method of Russell, the volume of distribution method of Fawdry, and a terminal slope method were less reliable, especially at low (0-60 ml/min) GFRs. The renal uptake method of Gates correlated poorly to the standards at all GFR levels even when corrected for body surface area or blood volume. The Russell two point and Jackson urinary GFR's can be used as complementary techniques and are recommended as primary methods of scintigraphic GFR determination.
