The incidence of pulmonary barotrauma during mechanical ventilation in children beyond the neonatal age group was studied in two groups of patients. In the first group, 179 cases of pediatric mechanical ventilation for over 12 hours were retrospectively analyzed for the occurrence of pneumothorax and pneumomediastrinum. Eleven percent (6 of 57) of young infants (0--6 months) without hyaline membrane disease and 3% (4 of 122) of older infants and children (over 6 months) developed these complications. Pulmonary barotrauma in young infants occurred only after cardiothoracic surgery and involved the same site as the intraoperative repair in all cases. Pulmonary barotrauma in older infants and children occurred in patients with severe respiratory disease requiring high peak airway pressures, PEEP, and respiratory rates. In the second group, the incidence of pulmonary barotrauma during ventilation with PEEP greater than or equal to 15 cm H2O was analyzed in 14 patients including 4 patients from the previous group. Overall, 64% (9 of 14) of this group developed pulmonary barotrauma and 43% (6 of 14) developed pneumothorax. Of 9 patients receiving PEEP greater than or equal to 15 cm H2O for longer than 24 hours, 6 developed pulmonary barotrauma after the first 24 hours. The incidence of pneumothorax and pneumomediastinum in ventilated infants without hyaline membrane disease and children is comparable to adult series. 相似文献

ABSTRACT: INTRODUCTION: Weaning protocols that include noninvasive ventilation (NIV) decrease re-intubation rates and ICU length of stay. However, impaired airway clearance is associated with NIV failure. Mechanical insufflation-exsufflation (MI-E) has been proven to be very effective in patients receiving NIV. We aimed to assess the efficacy of MI-E as part of an extubation protocol. METHOD: Patients with mechanical ventilation (MV) for more than 48 hours with specific inclusion criteria, who successfully tolerated a spontaneous breathing trial (SBT), were randomly allocated before extubation, either for (A) a conventional extubation protocol (control group), or (B) the MI-E extubation protocol (study group). During the postextubation period (48 hours), group A patients received standard medical treatment (SMT), including NIV in case of specific indications, whereas group B received the same postextubation approach plus three daily sessions of mechanical in-exsufflation (MI-E). Reintubation rates, ICU length of stay, and NIV failure rates were analyzed. RESULTS: Seventy-five patients (26 women) with a mean age of 61.8 ± 17.3 years were randomized to a control group (n = 40; mean SAPS II, 47.8 ± 17.7) and to a study group (n = 35; mean SAPS II, 45.0 ± 15.0). MV time before enrollment was 9.4 ± 4.8 and 10.5 ± 4.1 days for the control and the study group, respectively. In the 48 hours after extubation, 20 control patients (50%) and 14 study patients (40%) used NIV. Study group patients had a significant lower reintubation rate than did controls; six patients (17%) versus 19 patients (48%), P < 0.05; respectively, and a significantly lower time under MV; 17.8 ± 6.4 versus 11.7 ± 3.5 days; P < 0.05; respectively. Considering only the subgroup of patients that used NIV, the reintubation rates related to NIV failure were significantly lower in the study group when compared with controls; two patients (6%) versus 13 (33%); P < 0.05, respectively. Mean ICU length of stay after extubation was significantly lower in the study group when compared with controls (3.1 ± 2.5 versus 9.8 ± 6.7 days; P < 0.05). No differences were found in the total ICU length of stay. CONCLUSION: Inclusion of MI-E may reduce reintubation rates with consequent reduction in postextubation ICU length of stay. This technique seems to be efficient in improving the efficacy of NIV in this patient population. 相似文献

A constellation of adverse effects and complications may be associated with mechanical ventilation, although in many instances the causal role of the ventilator itself has not been established. Complications occur with greater frequency than is generally appreciated, and tend to be under-reported in the medical literature. Among the potential adverse physiologic effects of positive-pressure ventilation are decreased cardiac output, unintended respiratory alkalosis, increased intracranial pressure, gastric distension, and impairment of hepatic and renal function. Failure of the ventilator to cycle, of safety alarms to function properly, and of inspired gas to be properly heated or humidified are examples of equipment-related complications. Perhaps most feared among medical complications occurring during mechanical ventilation are pneumothorax, bronchopleural fistula, and the development of nosocomial pneumonia; these entities may owe as much to the impairment of host defenses and normal tissue integrity as to the presence of the ventilator per se. Finally, a variety of avoidable "misadventures," due primarily to lapses of understanding and communication among the physicians, nurses, and respiratory care practitioners managing the ventilated patient, can adversely affect comfort, morbidity, and ultimate outcome. 相似文献

Aim: Primary lymphedema requires continuous conservative treatment during the patient's life, which may affect their health‐related quality of life (HRQOL). Physical and psychosocial characteristics related to lymphedema are associated with their HRQOL. This study aimed to assess HRQOL in those patients undergoing conservative treatment and to determine the factors associated with their HRQOL. Methods: This was a cross‐sectional, observational study that included 83 patients with primary lymphedema at an outpatient clinic for lymphedema. HRQOL was assessed with the Medical Outcomes Study 36‐Item Short Form Survey (SF‐36) and EuroQol 5‐Dimension (EQ‐5D). Lymphedema status/complications and psychosocial status were evaluated by medical records, physical assessment, and self‐administrative questionnaires. Results: The general health perception score in the SF‐36 was lower than the age‐ and sex‐stratified national norms (P = 0.001). In the EQ‐5D, the proportions of patients with some/moderate or severe problems were 42.2% for pain/discomfort, 21.7% for usual activities, and 20.5% for anxiety/depression. By multiple regression analyses, a lower physical component summary score in the SF‐36 was associated with a higher lymphedema stage (P = 0.021), cellulitis within 30 days (P = 0.003), exercise (P = 0.010), and more substance use coping (P = 0.012). A lower mental component summary score was associated with skin lesions over edematous limbs (P = 0.008), less humor coping (P = 0.005), and more self‐blame coping (P = 0.014). Conclusion: Patients with primary lymphedema have problems in health perception, discomfort, usual activities, and anxiety/depression. Preventing cellulitis and skin lesions and humor coping may be able to improve HRQOL. 相似文献

Positive tip cultures and related risk factors associated with intravascular catheterization in pediatric cardiac patients 总被引:1,自引:0,他引:1
The incidence and risk factors of positive catheter tip cultures were studied prospectively in 392 consecutive children undergoing cardiac surgery under cover of cephalothin prophylaxis. A total of 1649 catheter tips were cultured and 58 (3.5%) yielded positive cultures. Specifically, the incidence of positive catheter tip cultures for iv, central venous, arterial and pulmonary arterial (PA) catheters was 0.9%, 5.9%, 3.9% and 10.6%, respectively, whereas one of the six surgically placed venous and arterial catheters had a positive tip culture and none of the 279 transthoracic catheters. Staphylococcus epidermidis was isolated from 79% of the positive tip cultures. Ten percent of the children had one or more positive tip cultures but none developed catheter-related septicemia or endocarditis. Stepwise logistic regression analysis revealed that longer in situ time (p less than .001), younger age (p less than .001), and inotropic support (p = .003) were significant independent predictors of risk for children developing positive catheter tip cultures. The safe in situ period for arterial, central venous, and PA catheters is 3 days in infants under 1 yr and 4 and 6 days for arterial and central venous catheters, respectively, in older children, if 0.95 cumulative probability of remaining free of a positive tip culture is accepted. The data generally support the bacteriologic safety of invasive hemodynamic monitoring in infants and children undergoing cardiac surgery. 相似文献

机械通气合并下呼吸道感染和多器官功能障碍患者的预后因素分析 总被引:4,自引:3,他引:4
目的:探讨影响机械通气合并下呼吸道感染和多器官功能障碍综合征(MODS)患者的预后因素,为提高机械通气抢救危重病成功率寻找途径。方法:收集120例接受机械通气治疗患者的临床资料,分析下呼吸道感染及MODS发生率与病死率之间的关系,比较MODS存活组与非存活组患者的基本特征(年龄、急性生理和慢性健康状况评分(APACHEⅡ评分)、是否合并慢性器官功能不全和其它部位感染、机械通气时间等)。结果:120例中有105例(87.5%)并发医院下呼吸道感染,分离出486株细菌,其中G^-杆菌350株(72.0%),尤以铜绿假单胞菌居多(212株,43.62%);79例(65.8%)发生MODS,其中48例(60.8%)死亡;未合并感染者死亡2例,单一细菌感染者死亡15例,混合细菌感染者死亡56例(P<0.005),且MODS存活组与非存活组患者在年龄,APACHEⅡ评分及机械通气时间3个方面差异有显著性(P<0.05或P<0.001)。结论:虽然机械通气治疗是危重病患者抢救中不可缺少的手段,但合并下呼吸道感染和MODS是这类患者病死率高的主要原因,其中感染病原菌种类、数量、年龄、APACHEⅡ评分及机械通气治疗时间可能是不容忽视的因素。 相似文献

OBJECTIVES: The efficacy of mechanical insufflation-exsufflation, in addition to standard chest physical treatments, was investigated as a first-line intervention for patients with neuromuscular diseases with respiratory tract infections and airway mucous encumbrance. DESIGN: The short-term outcomes of 11 consecutive neuromuscular disease patients with respiratory tract infections and tracheobronchial mucous encumbrance who were administered mechanical insufflation-exsufflation and conventional chest physical treatments in an intensive care unit were compared with the outcomes of 16 historical matched controls who had received chest physical treatments alone. Treatment failure was defined as the need for cricothyroid "minitracheostomy" or endotracheal intubation, despite treatment. The number of subjects administered bronchoscopy-assisted aspiration during the hospital stay was also compared. RESULTS: Treatment failure was significantly lower (P < 0.05) in the mechanical insufflation-exsufflation group than in the conventional chest physical treatments group (2/11 vs. 10/16 cases). The use of bronchoscopy-assisted aspiration was similar in the two groups (5/11 vs. 6/16 cases). Mechanical insufflation-exsufflation did not produce serious side effects and was well tolerated by all subjects. CONCLUSIONS: Provision of mechanical insufflation-exsufflation in combination with standard chest physical treatments may improve the management of airway mucous encumbrance in neuromyopathic patients; its use should be included in the noninvasive approach to treatment of respiratory tract infections with impaired mucous clearance. 相似文献
