ObjectiveTo systematically review the risk factors leading to postoperative persistence of children diagnosed with obstructive sleep apnea (OSA) after adenoidectomy and tonsillectomy. MethodsPubMed, EMbase, The Cochrane Library, ClinicalTrials.gov, CNKI, VIP, WanFang Data and SinoMed databases were electronically searched to collect case-control studies and cohort studies related to risk factors for postoperative persistence of OSA in children from inception to July 2019. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 12 cohort studies involving 1 659 OSA patients were included. Meta-analysis results showed that the risk of postoperative persistence of OSA in children with preoperative obesity was 3.47 times higher than that in non-obese children (RR=3.47, 95%CI 2.04 to 5.92, P<0.000 01). Compared with normal-weight children, obese children had 4.11 times higher risk of postoperative residual OSA (RR=4.11, 95%CI 1.68 to 10.07, P<0.000 01).ConclusionsPreoperative obesity is a risk factor for postoperative persistence of OSA in children. Due to the limited quantity and quality of included studies, more high-quality studies are needed to verity the above conclusions.
Objective To review the research progress of rapid surgery for hip fracture in elderly patients. Methods The published studies, expert consensus, and guidelines at home and abroad were systematically summarized from the aspects of the characteristics of aging population, the benefits of rapid surgery, the disadvantages of delayed surgery, and the recommendations of current guidelines, so as to further guide clinical practice. Results Hip fracture is a common fracture type in the elderly population. As elderly patients generally have poor physique and often have a variety of underlying diseases, such as hypostatic pneumonia, bedsore, lower limb vein thrombosis, and other complications in conservative treatment, its disability rate and mortality are high, so surgical treatment is the first choice. At present, most relevant studies and expert consensus and guidelines at home and abroad support rapid surgery, that is, preoperative examination should be started immediately after admission, and adverse factors such as taking anticoagulant drugs, serious cardiovascular diseases, and severe anemia should be clearly and actively corrected, and surgery should be completed within 48 hours after admission as far as possible. Rapid surgery can not only significantly reduce the mortality of patients, but also reduce the length of hospital stay and the incidence of perioperative cognitive impairment, which is conducive to the recovery of patients with pain during hospitalization and postoperative function, and improve the prognosis of patients. Conclusion In order to avoid many problems caused by delayed surgery, the elderly patients with hip fracture should be operated as soon as possible under the condition of actively correcting the adverse factors. Comprehensive evaluation and preparation, the development of an individualized surgical plan, and the formation of a multidisciplinary medical team can reduce surgical risks and improve effectiveness.
