ABSTRACT
OBJECTIVE To explore the efficacy and safety of intra-articular injection of ropivacaine combined with alfentanil for postoperative analgesia in patients who underwent knee arthroscopic surgery. METHODS A total of 60 patients who underwent knee arthroscopic surgery were collected from the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture from March to September in 2022， and then divided into trial group and control group with random number table method， with 30 cases in each group. The control group received intra-articular injection of 0.25% ropivacaine 50 mg， and the trial group received intra-articular injection of 0.25% ropivacaine 50 mg+alfentanil 0.15 μg/kg.The first postoperative remedial analgesia time， the total amount of postoperative remedial drugs， numerical rating scale at rest （NRS-R） scores， numerical rating scale at movement （NRS-M） scores， heart rate， mean arterial blood pressure， and pulse oxygen saturation during exercise at different monitoring time points after surgery， the incidence of adverse drug reactions such as hypotension， respiratory depression， nausea， and vomiting after surgery were compared between 2 groups. RESULTS Compared with the control group， the first postoperative remedial analgesia time was significantly longer in the trial group， and the total amount of postoperative remedial drugs was significantly reduced （P＜0.001）. The trial group had lower NRS-R and NRS-M scores at each monitoring time point， with statistically significant differences （P＜0.001）， and there was an interactive effect between time and groups （P＜0.001）. The changes in heart rate， mean arterial blood pressure， and pulse oxygen saturation of patients in the trial group were relatively small， with no statistically significant differences （P＞0.05）， and there was no interactive effect between time and groups （P＞0.05）. There was no statistical significance in the incidence of adverse drug reactions between 2 groups， such as postoperative hypotension， respiratory depression， nausea， vomiting （P＞0.05）. CONCLUSIONS The intra- articular injection of ropivacaine combined with alfentanil shows good efficacy and safety for post-knee arthroscopic analgesia， and significantly prolongs the analgesic duration of ropivacaine.
ABSTRACT
Objective:To explore the effects of risk grading nursing on the prevention of postoperative deep vein thrombosis (DVT) and quality of life in patients undergoing knee arthroscopic surgery.Methods:A total of 1 140 patients undergoing knee arthroscopic surgery in Beijing Jishuitan Hospital were selected. The 529 cases with routine nursing from January to December 2018 were selected as the control group, while another 611 cases with risk grading nursing from January to December 2019 were selected as the observation group. The incidence of DVT, limbs swelling, quality of life and nursing satisfaction were compared between the two groups.Results:The incidence of DVT and the positive rates of Homan sign and Neuhof sign were 2.78% (17/611), 3.93% (24/611), 4.91% (30/611) in the observation group, and 5.10% (27/529), 10.02% (53/529), 11.72% (62/529) in the control group, the differences were statistically significant ( χ2=4.12, 16.70, 17.72, all P<0.05). The peripheral diameter and body surface temperature at 5 cm above the ankle, 10 cm below the patella and 15 cm above the patella were (21.30 ± 1.72) cm, (34.89 ± 2.75) cm, (46.69 ± 4.58) cm, (33.14 ± 1.40) ℃, (34.45 ± 1.52) ℃, (35.22 ± 1.36) ℃ in the observation group, and (22.88 ± 1.43) cm, (35.91 ± 1.81) cm, (49.18 ± 4.23) cm, (34.39 ± 1.22) ℃ (35.88 ± 1.49) ℃, (35.97 ± 1.31) ℃ in the control group, the differences were statistically significant ( t values were -16.74--7.25, all P<0.05). The scores of general health, physiological function, physiological function, mental health, social function, emotional function, body pain and body vitality were (75.84 ± 5.33), (79.78 ± 5.71), (76.71 ± 4.14), (84.91 ± 4.15), (75.53 ± 4.19), (78.80 ± 6.76), (74.85 ± 3.49), (78.61 ± 3.52) points in the observation group, and (71.39 ± 4.28), (75.44 ± 6.26), (73.05 ± 4.09), (80.15 ± 6.87), (71.66 ± 4.18), (74.89 ± 6.23), (71.14 ± 5.20), (74.66 ± 5.14) points in the control group, the differences were statistically significant ( t values were 10.10-15.57, all P<0.05). The satisfaction scores of nursing communication, safety, nursing technology, nursing, guidance and physical environment were (4.54 ± 0.42), (4.75 ± 0.46), (4.54 ± 0.52), (4.60 ± 0.48), (4.60 ± 0.53), (4.30 ± 0.64) points in the observation group, and (3.93 ± 0.34), (3.98 ± 0.37), (3.96 ± 0.41), (3.93 ± 0.38), (3.85 ± 0.36) (3.74 ± 0.38) points in the control group, the differences were statistically significant ( t values were 17.62-30.82, all P<0.05). Conclusions:Risk grading nursing is beneficial to alleviate postoperative limb swelling in patients after knee arthroscopic surgery, reduce incidence of DVT, improve quality of life and nursing satisfaction.
ABSTRACT
Objective To explore the effect of immobilization with plaster cast applying in children's rehabilitation after knee arthroscopic surgery,and discuss the clinical significance of immobilization with plaster cast in children's rehabilitation after knee arthroscopic surgery.Methods A total of 72 objectives suffered from knee joint diseases were chosen and received knee arthroscopic surgery from January 2013 to November 2014.They were classified into the experimental group and the control group with the random digit table with 36 patients in each group.The control only underwent the regular rehabilitation exercise.The experimental group was given fixation with plaster caster before they got rehabilitation exercise.The three indexes such as pain degree,the compliance of children knee function exercise and the range of knee motion in different time courses were compared after operation.Results The VAS pain scores of the experimental group and the control group were (2.12±0.70),(2.37±0.61) respectively with statistical significance,P＜0.05.On the third day,one week and two weeks after operation,the complete compliance of children with knee function exercise was 83.3％ (30/36) vs.8.3％ (3/36),97.2％ (35/36) vs.22.2％ (8/36),97.2％ (35/36) vs.22.2％ (8/36) in the experimental group and the control group,Z values were-6.343,-6.400,-6.400,P＜ 0.01.On the second,third and fourth weeks after operation,the good rates of knee motion range in the experimental group and the control group were 50.0％ (18/36) vs.16.7％ (6/36),94.4％ (34/36) vs.83.3 (30/36),97.2％ (35/36) vs.81.6％ (31/36),Z values were-3.345,-2.861,-2.012,P＜0.01.Conclusions The use of immobilization with cast plaster in children's rehabilitation after the knee arthroscopic operation could significantly relieve the pain brought by the surgery,as well as increase the level of appliance of knee function exercises and improve the range of knee motion greatly.Therefore,it could help children to restore the knee function earlier and furthermore to promote life quality after receiving knee arthroscopic surgery.
ABSTRACT
BACKGROUND: Tourniquet deflation during lower extremity surgery affects the hemodynamics and metabolism of the patient, which can affect brain activity. This study examined the changes in brain activity during tourniquet deflation by measuring the bispectral index (BIS). METHODS: The BIS was measured during surgery in forty patients who had received knee arthroscopic surgery under general anaesthesia. The BIS was measured 5 minutes before deflation (DB5) and 5 minutes after deflation (DA5). RESULTS: The BIS at DB5 and DA5 was 50.2 +/- 9.9 and 44.4 +/- 10.4, respectively. The BIS of DA5 was significantly lower than that of DB5 (P < 0.05). CONCLUSIONS: Tourniquet deflation during lower extremity surgery decreases the BIS associated with hemodynamic and metabolic changes. However, its clinical significance in neurologically critical patients, such as geriatric or neurologically disabled patients, remains to be clarified.
