BACKGROUND AND OBJECTIVES Lidocaine could provide many advantages in continuous regional anesthesia techniques, including faster onset, greater titratability, and lower cost than long-acting local anesthetics. This prospective, randomized, double-blinded, pilot study is therefore intended to compare lidocaine to ropivacaine in bilateral continuous paravertebral blocks using a multimodal approac...

BACKGROUND Allocation of the correct amount of operating room (OR) "block time" can provide surgeons with access to sufficient OR time to complete their elective cases while optimally matching staffing with the elective case workload (to maximize labor productivity). To evaluate how to predict accurately total hours of elective cases performed by a surgical group using data from surgical servic...

Peak expiratory flow rate (PEFR) variability follows a specific pattern in asthmatics as well as in healthy individuals. There is scarcity of data for Indian healthy subjects. The PEFR (L/min.) was measured with Wright's portable peak flow meter at 05:00, 8:00, 11:00, 14:00, 17:00, 20:00 and 23:00 hours in 42 healthy, non-smoking adults of age group between 18-26 years. The variability of PEFR ...

BACKGROUND AND AIM Thoracoscopy is a diagnostic tool superior to other available techniques for the assessment of pleural effusions. There are numerous publications that describe the technique in detail but there is very little published on the optimal time of chest drain removal post procedure. Our aim was to retrospectively study all cases of diagnostic thoracoscopy and to ascertain the time ...

Abstract This paper examines the extent to which incidence of dual job holding is cyclically sensitive in context hours constraints on a worker’s weekly labor supply their main job. Random effects logit models probability are estimated separately for men and women each three mutually exclusive, hours-constrained regimes: overemployment, unconstrained hours, underemployment. As measured by devia...

abstract introduction: due to the increasing number of breast masses and a more precise attention to them, a greater number of patients refer to clinics for biopsy or resection of breast and axillary lymph nodes. an appropriate anesthesia method can decrease hospitalization time, its expenditure and postoperative complications. paravertebral anesthesia [1] is a simple and feasible method in mos...

Abstract Introduction Pilots flying long range (8-16 h) and ultra (16+ flights crossing several time zones must decide when how much to sleep during layover between the outbound return flight. Some pilots choose on home base (HBT), while others attempt local time. We sought broad patterns in timing amount of pilot layovers. Methods Using actigraphy, verified by self-report diaries, we collected...

For SAT and CIRCUIT -SAT there is an obvious brute force algorithm that requires 2m time where n is the number of variables and m is a measure of the overall input size. How much better we can seems to depend on the input structure. In the case of kSAT there are some improvements. Theorem 1.1 (Paturi-Pudlak,Schöning,Paturi-Pudlak-Saks-Zane,Hertli). For constants 1 ≤ c ≤ 2, there are (randomized...

OBJECTIVE To evaluate the feasibility of laparoscopy assisted total mesorectal excision (TME) for rectal cancer. METHOD From March 2000 to November 2003,67 patients with rectal cancer received laparoscopy assisted TME,in whom 45 cases received anterior resection (AR),and 22 cases received abdominal perineal resection (APR). RESULTS The operation was performed according to the rules of TME. ...
