【摘要】目的探討喉癌手術后患者對兩種不同霧化方式的耐受性,為選擇最佳霧化方式提供參考。方法將49例喉癌手術后患者隨機分為觀察組(25例)和對照組(24例),觀察組采用氧氣霧化吸入,對照組采用空氣壓縮泵霧化吸入。分別記錄兩組患者霧化吸入前及吸入15 min時脈搏血氧飽和度(SpO2)及心率;霧化過程中患者有無心慌、氣緊等不適以及霧化后痰液的性質及量。采用SPSS 13.0軟件進行統計分析。結果兩組患者霧化吸入15 min時的SpO2差異有統計學意義(Plt;001),觀察組高于對照組;而兩組患者霧化吸入前SpO2、心率、不適主訴及霧化后痰液的性質差異均無統計學意義(Pgt;005)。結論氧氣霧化吸入可以提高喉癌手術后患者霧化過程中的SpO2,使患者感覺更加舒適。【Abstract】Objective To investigate postoperative patients with laryngeal carcinoma atomization of two different forms of tolerance, in order to choose the best means of atomization. Methods Fifty postoperative patients with laryngeal carcinoma were divided into observation group using oxygen inhalation and control group using the air compression pump inhalation. Two groups of patients were recorded the value of SpO2 and heart rate before 15 minutes after the inhalation,as well as the discomforts such as flustered,gas tight during the atomization process and the nature and olume of sputum. Results The results of two groups of patients at the time of 15 minutes inhalation SpO2 statistically significant difference (Plt;001), the observation group than in the control group average SpO2 high; and two groups of patients with preinhalation SpO2 average, average heart rate, Discomfort chief complaint and the nature of sputum after aerosol compared no significant difference (Pgt;005). Conclusion Oxygen inhalation in patients with laryngeal cancer can improve the atomization process SpO2 value, so that patients feel more comfortable.
ObjectiveTo systematically review the clinical effects of non-humidified versus humidified low-to-moderate flow oxygen inhalation therapy via nasal cannula.
MethodsRandomized controlled trials (RCTs), clinical controlled trials (CCTs) and cross-over studies about the clinical effects of non-humidified versus humidified low-to-moderate flow nasal cannula oxygen inhalation therapy in hospitalized adult patients were searched in The Cochrane Library (Issue 3, 2016), The Joanna Briggs Institute Evidence Based Practice (EBP) Database, EMbase, PubMed, Web of Science, CBM, CNKI, VIP and WanFang Data from inception to March 2016. Three reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software.
ResultsA total of nine RCTs and three CCTs involving 3 756 patients were finally included. The results of meta-analysis indicated that: non-humidified was superior to humidified oxygen therapy in reducing bacterial contamination of oxygen apparatus (P < 0.05) and the time of daily replacement of sterile water oxygen humidifier bottles (P < 0.05), while the two groups were alike in relieving nasal dryness (RR=1.08, 95%CI 0.91 to 1.29, P=0.37), nasal bleeding (RR=1.17, 95%CI 0.66 to 2.08, P=0.59) and discomfort (RR=0.80, 95%CI 0.56 to 1.14, P=0.22).
ConclusionCurrent evidence indicates that there is no significant difference between non-humidified and humidified low-to-moderate flow nasal cannula oxygen inhalation therapy in relieving patients' nasal dryness, nasal bleeding and discomfort. But non-humidified oxygen therapy can reduce bacterial contamination of oxygen apparatus, simplify the operation procedures and lessen nurses' operation time.
High-flow nasal cannula (HFNC) oxygen therapy, which is important in noninvasive respiratory support, is increasingly being used in critically ill neonates with respiratory failure because it is comfortable, easy to set up, and has a low incidence of nasal trauma. The advantages, indications, and risks of HFNC have been the focus of research in recent years, resulting in the development of the application. Based on current evidence, we developed guidelines for HFNC in neonates using the grading of recommendations assessment, development and evaluation (GRADE). The guideline was formulated after extensive consultations with neonatologists, respiratory therapists, nurse specialists, and evidence-based medicine experts. We have proposed 24 recommendations for 9 key questions. This guideline aims to be a source of evidence and references of HFNC oxygen therapy in clinical practice, and so that more neonates and their families will benefit from HFNC.
ObjectiveTo assess the effect of prolonged oxygen inhalation after total hip arthroplasty (THA) on early postoperative rehabilitation in elderly patients.MethodsPatients who underwent primary unilateral THA from June to December 2018 were divided into a conventional oxygen inhalation group (control group) and a prolonged oxygen inhalation group (trial group) according to a random number table. The control group received oxygen inhalation via a single nasal catheter from their return to the ward after surgery until 08:00 a.m. on the first day postoperatively. In addition to routine oxygen inhalation, the trial group received oxygen inhalation during the rehabilitation exercise in bed and before half an hour of floor activities on the first and second day after operation. Oxygen saturation, heart rate, respiratory rate, blood pressure, pain, fatigue score, hip mobility and Pittsburgh Sleep Quality Index (PSQI) scores were recorded and analyzed at 24 and 48 hours after surgery.ResultsA total of 60 patients were included finally, 30 patients in each group. At 24 and 48 h after surgery, the differences were statistically significant in the respiratory rate [(20.30±1.20) vs. (21.40±1.04) breaths per minute, (18.87±1.14) vs. (22.03±0.85) breaths per minute], oxygen saturation [(94.70±2.34)% vs. (90.60±0.73)%, (96.40±1.81)% vs. (91.20±0.85)%］, abduction angles of hip joint [(33.50±5.44) vs. (29.31±5.30)°, (38.67±2.60) vs. (33.00±4.84)°], pain scores (3.03±1.27 vs. 5.07±1.14, 1.43±0.97 vs. 3.60±1.13) and fatigue scores (4.17±1.34 vs. 8.20±0.61, 3.23±1.38 vs. 7.43±1.19) between the trial group and control group (P<0.05). PSQI scores (2.20±0.76 vs. 3.97±0.76) on the first day after surgery, and hip flexion [(105.17±4.82) vs. (99.50±2.40)°] , heart rate [(72.86± 6.38) vs. (79.40±3.97) beats per minute], diastolic blood pressure [(71.43±10.24）vs. (77.57±4.59) mm Hg (1 mm Hg=0.133 kPa)] at 48 h after surgery in the trial group were better than the those in control group (P<0.05).ConclusionCompared with conventional oxygen inhalation, prolonged oxygen inhalation after THA in elderly patients can improve postoperative pain, fatigue, sleep and hip function.
