A cold floating probe method was compared with the emissive floating probe method in terms of a low-pressure radio-frequency inductive *** dependences of difference between the plasma potential and the floating potential on the electron temperature 1-8 eV,plasma density 109-1012 cm 3 and magnetic field 100-650 G were *** was demonstrated that the difference between the potentials that obtained by these two methods can differ significantly from the expected value of 5.2 kTe/e for argon.

Objective: To compare the efficacy and acceptability of sameday misoprostol and overnight laminaria for cervical ripening before early second-trimester surgical abortion. Methods: We performed a randomized, double-blinded, controlled trial comparing 400 μ g of vaginal misoprostol, given 3-4 hours preoperatively, with overnight laminaria before early secondtrimester surgical abortion among women at 13.0-16.0 weeks of gestation (n = 84). The primary outcome was procedure time, and the sample size was based on 95% power to detect a difference of 4.5 minutes between groups. Secondary outcomes included completion of the procedure on the first attempt, procedural difficulty, and patients’ pain scores and preferences. Results: The average gestational duration was 14 weeks 6 days. Procedures performed after laminaria were significantly faster than those after misoprostol (median 3.4 versus 7.2 minutes, re-spectively, P =.01). Laminaria patients had significantly greater dilation than misoprostol patients at abortion (mean 43 versus 33 French, P <.001), and more misoprostol patients required additional dilation (85% versus 21% , P <.001). Physicians rated 27% of the misoprostol procedures as moderate-markedly difficult versus 5% of laminaria procedures (P =.01). Differences in efficacy were pronounced among nulliparous patients. There were no significant differences in ability to complete the procedure on the first attempt or patients’ intraoperative pain scores. More women in the misoprostol group would choose their assigned method again (93% versus 62% , P <.01), and 82% of all subjects preferred a 1-day procedure. Conclusion: Early second-trimester abortions take longer and are technically more challenging after cervical ripening with same-day misoprostol than with overnight laminaria, but patients prefer same-day misoprostol.

OBJECTIVE: To evaluate obstetrics and gynecology resident satisfaction with a comprehensive, integrated abortion rotation. METHODS: The University of Californ ia, San Francisco obstetrics and gynecology residency program includes a 6-week PGY-3 family planning rotation at an in-hospital clinic where abortions are p rovided up to 23 weeks of gestation. Residents annually evaluate the educational value of all clinical rotations on a 5-point Likert scale, with 5 indicating " maximum value," and 1 "no value." Using data from 1998-2003, we compared rating s of the family planning rotation with all other PGY-3 rotations. We also surve yed residents 1 to 3 years after graduation to assess the rotation qualitatively and quantitatively. RESULTS: Forty residents completed the abortion training, n one opted out of training, and all completed the evaluations. Of all rotations i n the third year, the family planning rotation was the highest rated (4.70), was similar in value to a high-volume surgical rotation (4.51, P >.10) and the ele ctive rotation (4.45, P >.05), and surpassed the average score for all inpatient rotations (4.00, P < .001), continuity clinic (4.10, P < .001), and outpatient clinical experiences (4.06, P < .01). According to residency graduates, the fami ly planning rotation was rated 4.8 (where 5 indicates “far greater value”than other rotations), and 85%of respondents rated it of “maximum learning value.” CONCLUSION: Obstetrics and gynecology residente place high value in the Universi ty of California, San Francisco PGY-3 family planning rotation during their tra ining and in their first years of practice.
