PurposeThis article reviews state of the science of preoperative risk factors associated with postanesthesia care unit (PACU) pediatric respiratory complications.DesignAn integrative review.MethodsA search of PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, Scopus, Cochrane, and Joanna Briggs Institute databases was performed. Thirty-one articles, published between 2006 and 2018, were appraised for quality and the level of evidence using the Johns Hopkins Nursing Evidence-Based Practice Model.FindingsThese articles were grouped into the following categories: age, American Society of Anesthesiologists status, gender, airway comorbidities, syndromes, anomalies, pulmonary comorbidities, ethnicity, obesity, neurologic comorbidities, and cardiac comorbidities.ConclusionsEvidence identified significant preoperative and anesthesia risk factors that are associated with PACU pediatric respiratory complications. This article reveals the importance for the perioperative team to identify, assess for, communicate, and develop a management plan for pediatric respiratory complications. 相似文献

In order to decrease the perioperative complications by preoperative cisplatin chemotherapy, the preoperative single administration of cisplatin (30 mg/m2) was performed weekly from one to six times in 36 consecutive patients with esophageal cancer classified as higher than Stage II. The survival curve of 17 patients in Stage III was significantly better (P<0.05) than that of patients who had been treated without preoperative cisplatin treatment. In 3 of the 12 patients who had locally invasive cancer, either the main tumors or the metastatic lymph nodes, which had invaded the trachea or the left main bronchus, sufficiently receded, so that a curative esophagectomy became possible; 2 of them have survived over 33 months while 1 died of pneumonia 33 months after surgery. The number of perioperative complications was minimal, and thus, we consider that the postoperative use of cisplatin and fluorouracil is indicated in patients in whom a histological response is noted in the resected specimens.This work was partially supported by Grant No. 02454315 from the Japanese Ministry of Education 相似文献

The indications, contraindications and complications of percutaneous laparoscopic cholecystectomy (PLC) were established from a group of 308 patients referred for cholecystectomy. Of the 308 patients 86% underwent PLC, 5% were commenced laparoscopically, but converted to open cholecystectomy and 9% were performed as open cholecystectomy from the outset. Complications included two bile leaks from the gall-bladder bed, one cystic duct stump leak and three retained stones. Pre-operative rather than intra-operative duct imaging was used so that common duct stones could be removed before operation. PLC is a safe procedure that has now become the standard technique for cholecystectomy. 相似文献

The purpose of this study was to evaluate the acute effects of corticosteroid and iodide preoperative therapy in patients
with Graves' disease in terms of thyroid function and immunological parameters. The above combination was prescribed for 4
patients who had experienced severe side effects from antithyroid drugs (ATD) in order to reduce the possibility of post-thyroidectomy
thyroid storm. Corticosteroids were employed daily for four days, and iodides were given daily for two weeks prior to thyroidectomy.
The free T3 values decreased rapidly to euthyroid levels following the administration of both drugs, although the free T4 values were still much higher than normal in 3 of the 4 patients at the time of surgery. By comparison, 3 of 8 patients treated
with ATD also had thyroid hormone levels above normal. Studies of lymphocyte subsets revealed that the percentage of helper
T cells was significantly less in the corticosteroidiodide treatment group than in the control and ATD groups. It is thus
possible that postoperative thyroid storm might be prevented through corticosteroid-iodide therapy by virtue of the reduction
of free T3 values to within the normal range by the time of surgery. The acute suppression of helper T cells was another result of this
form of therapy observed. 相似文献

? The benefits of informing patients before undergoing surgery or other investigative procedures are clearly demonstrated in the literature. ? This study aimed to determine the amount and type of information given to patients before, during and after undergoing gastroscopy investigations. ? A survey approach incorporating structured interviews and structured observation was utilized. ? There were statistically significant differences between the information acquired by younger and older patients prior to, but not during or after, the procedure. ? Nurses appear to be the most important source of information for older patients while the information leaflet was perceived as the most important source of information for younger patients. 相似文献

Background : Patients' desire for information about anaesthesia has been examined in a number of Commonwealth countries but not in Scandinavia. A questionnaire was distributed to form a basis for giving Danish patients more appropriate preoperative information.
Methods : 201 preoperative patients in Denmark were asked to complete a questionnaire. The patients were divided into subgroups according to: age, gender, residential origin, ASA group, educational level, type of anaesthesia planned and number of previous anaesthetics.
Results : Patients from a city area required significantly more information than patients from a rural/urban area about pre-medication drugs, drips/catheters, pain/pain relief and complications. Men more than women preferred to know about dangerous complications. Information about pain /pain relief, duration of anaesthesia, and influence of anaesthesia on daily activities such as eating, drinking, mobilisation was given the highest priority, while unpleasant information such as about complications and needles was given the lowest priority. Meeting the anaesthetist and information about alternative methods of anaesthesia and premedication drugs were given only moderate priority. Ranking information in Denmark was significantly correlated with Scotland, Canada and Australia, despite profound differences in priority. More often than Danish patients, Australian patients felt they had right to know, and especially about complications.
Conclusion : Patients from a city area required more information than patients from a rural/urban area. Information about the influence on daily activities was preferred to unpleasant information. Ranking information in Denmark was correlated with a number of Commonwealth countries. 相似文献
