Morbidity and Mortality in 1022 Consecutive Living Donor Nephrectomies: Benefits of a Living Donor Registry
Lightfoot JT, Hilton F Jr, Fortney SM. Aviat Space Environ Med. 1991 Jan;62(1):19-25
Quantifying the risks of living donation is important information for potential living donors and members of the transplant team. This registry includes all donors over a 12-year period. Major postoperative complications occurred in 3% of patients, while minor complications, mostly UTIs, occurred in 18%. There were no deaths.

Abstract:
Data on repeatability and comparability of different presyncopal symptom-limited lower body negative pressure (PSL-LBNP) exposure protocols, while scarce, are critical to the interpretation of studies using PSL-LBNP methods. To investigate if PSL-LBNP tolerance, heart rate, and blood pressure were repeatable, 11 subjects were exposed to 4 PSL-LBNP tests; each test occurring at the same time of day, separated by at least 72 h, and using the same protocol. No significant differences were found in either the heart rate or blood pressure responses to the PSL-LBNP or the tolerance indices (cumulative stress index; maximum negative pressure tolerated; and duration of negative pressure exposure). To study the comparability of different PSL-LBNP protocols, nine subjects were exposed randomly to five PSL-LBNP tests using protocols that varied in stage duration but not pressure profile. The protocols had 1-, 3-, 5-, 7-, or 9-min stage durations. These PSL-LBNP exposures were conducted at the same time of day and separated by at least 72 h. While no differences were noted in either the response pattern or magnitude of heart rate or blood pressure to the differing protocols, the cumulative stress index and the duration of negative pressure exposure varied proportionally with the length of the stage durations. With the exception of the 1-min protocol, the maximum negative pressure tolerated did not vary regardless of the protocol used.(ABSTRACT TRUNCATED AT 250 WORDS)
