Is routine extubation overnight safe in cardiac surgery patients?

Objectives

Expedient extubation after cardiac surgery has been associated with improved outcomes, leading to postoperative extubation frequently during overnight hours. However, recent evidence in a mixed medical-surgical intensive care unit population demonstrated worse outcomes with overnight extubation. This study investigated the impact of overnight extubation in a statewide, multicenter Society of Thoracic Surgeons database.

神经外科重症监护病房常见病原菌的分布与耐药性研究

目的调查珠江医院神经外科重症监护病房(ICU)病原菌的分布与耐药情况,分析ICU院内感染的发生原因,探讨防治对策。方法应用法国VITEKⅡ全自动细菌鉴定仪鉴定病原菌,用纸片扩散法检测药敏结果。结果神经外科ICU菌群主要以革兰阴性杆菌(71.6%)为主,鲍曼不动杆菌占16.7%,大肠埃希菌占15.7%,铜绿假单胞菌占13.7%,肺炎克雷伯菌占13.7%等。但葡萄球菌、粪肠球菌等阳性球菌(28.4%)也有增加的趋势。亚胺培南和头孢哌酮/舒巴坦仍保持最高抗菌活性,细菌的耐药率分别为15.3%和30.6%。结论我院神经外科ICU感染主要病原菌是革兰阴性杆菌,对常用抗菌药物耐药性较高,但革兰阳性球菌所占比例呈增高趋势。控制第二、三代头孢菌素以及制酸剂(质子泵抑制剂)的预防性用药,减少耐药菌株的产生,有针对性地使用抗生素是控制危重病人感染的有效措施。     

Impact of ceftazidime restriction on gram-negative bacterial resistance in an intensive care unit

The present study included three periods: (1) a 12-month prerestriction and control period in 2001; (2) a 12-month restriction period with reduced ceftazidime prescribing in favor of piperacillin-tazobactam (2002); (3) and a 24 month postrestriction period (2003–2004). Note that, for results, P represents the difference between 2002 and 2001; P′, the difference between 2003 and 2001; and P″, the difference between 2004 and 2001. No changes in hygiene practices were observed during these three periods. The purpose of this study was to assess the effect of reducing ceftazidime use in an intensive care unit (ICU) upon Gram-negative bacterial resistance, particularly as regards Pseudomonas aeruginosa. During the three periods of the study, patients were similar concerning age, Simplified Acute Physiology Score (SAPSII), the site of nosocomial infection, and the requirements for mechanical ventilation (75% in 2001, 76% in 2002, 74% in 2003, and 85% in 2004). The most commonly isolated pathogens were P. aeruginosa, Acinetobacter baumannii, and Enterobacteriaceae. The use of ceftazidime decreased significantly from 12.6% in 2001 to 9% in 2002, to 3% in 2003 (P′ = 0.0009), and 2.6% in 2004 (P″ = 0.0001) in favor of piperacillin-tazobactam (0% 2001 to 3.7% in 2003; P′ = 0.002; and 5% in 2004; P″ = 0.0001). Simultaneously, we observed a significant decrease in isolates of P. aeruginosa resistant to piperacillin-tazobactam (P = 0.03; P′ = 0.004; P″ = 0.009), and those resistant to imipenem in 2003 (P′ = 0.008). We also noted a significant decrease in A. baumannii isolates resistant to ceftazidime (P′ = 0.01; P″ = 0.0004) and those resistant to imipenem in both 2002 and 2004 (P = 0.03; P″ = 0.04), and a considerable decrease in isolates of Klebsiella pneumoniae producing expanded spectrum betalactamase (ESBL) in 2003 and 2004 (P′ = 0.04; P″ = 6.10⁻⁵). In contrast, we noted an increase in penicillinase-producing isolates of K. pneumoniae, from 6% in 2001 to 16% in 2002 (p = 0.01), 20% in 2003 (P′ = 0.001), and 32% in 2004 (P″ = 10⁻⁶). We concluded that restriction of ceftazidime use was demonstrated to be efficient in reducing antimicrobial resistance, especially to K. pneumoniae ESBL.
