RESUMEN
Objective To analyze the characteristics of lower respiratory tract infection occurring in patients after craniocerebral surgery in Intensive Care Unit (ICU) and explore its nursing countermeasures. Methods Sixty-eight patients with lower respiratory tract infection after craniocerebral surgery in the ICU of the First Affiliated Hospital of Wenzhou Medical University from January 2015 to March 2016 were selected as the study subjects. All patients were treated with dehydration to reduce intracranial pressure, hemostasis, anti-infection, anti-epilepsy, mild hypothermia, hypoglycemia and other symptomatic supportive treatments, and the corresponding nursing measures were given. The patients' primary diseases and etiological examination results were analyzed. Results Of the 68 patients complicated with lower respiratory tract infection after craniocerebral surgery, the majority of primary disease was craniocerebral injury, accounting for 45.59% (31/68). A total of 127 strains of pathogenic bacteria were isolated, mainly Gram-negative (G-) bacteria [92 strains (accounting for 72.44% )];followed by Gram-positive (G+) bacteria [19 strains (accounting for 14.96%)] and fungi [16 strains (accounting for 12.60%)]. The main pathogens of G- were Acinetobacter baumannii 21 strains (accounting for 23.14%), Klebsiella pneumoniae 13 strains (accounting for 14.94%), Burkholderia cepacia 10 strains (accounting for 11.49%), Pseudomonas aeruginosa 8 strains (accounting for 11.49%); the main pathogens of G+ was Staphylococcus aureus 6 strains (accounting for 5.89%). Conclusion The incidence of lower respiratory tract infection in ICU patients after craniocerebral surgery is high. It is necessary to prevent and control the related risk factors as soon as possible, and take energetic and effective nursing measures to reduce the incidence of lower respiratory tract infection.
RESUMEN
BACKGROUND:There are various commonly used interbody fusion methods, such as autologous bone, al ograft bone and titanium-based posterior lumbar interbody fusion, and each method has its own advantages and disadvantages. OBJECTIVE:To observe the clinical efficacy of a bioactive nano-hydroxyapatite/polyamide 66 fusion cage in posterior lumbar interbody fusion for the treatment of lumbar disease. METHODS:A retrospective case analysis was conducted on 16 cases treated with posterior lumbar interbody fusion at the Department of Orthopedic, the First Affiliated Hospital of Gannan Medical University from July 2010 to December 2011, and al the patients were implanted with nano-hydroxyapatite/polyamide 66 biological activity fusion cage. RESULTS AND CONCLUSION:Al the patients were fol owed-up for 10-24 months, and the lumbar pain was significant improved, the lumbar visual analogue score, lumbar Japanese Orthopaedic Association score and Oswestry disability index score were significantly improved during the final fol ow-up period (Pfusion without nano-hydroxyapatite/polyamide 66 fusion cage displacement or subsidence. The results indicate that nano-hydroxyapatite/polyamide 66 fusion cage for the treatment of posterior lumbar interbody fusion can reconstruct the lumbar stability and provide immediate stability after implantation, and has good biological activity.
