Objective To observe the effect of combined continuous femoral nerve blockade (CFNB)with epidural morphine postoperative analgesia on total knee arthroplasty (TKA)in elderly patients.Methods Eighty elderly patients scheduled to undergo TKA were randomly divided into two groups:groups FN and FNM.Groups FNM and FN were received 0.1% morphine 2 ml and normal saline 2 ml through epidural space respectively at the end of surgery.After surgery,all patients were implanted catheter around femoral nerve guided by ultrasound,and were infused 0.2% ropivacaine 25 ml.Continuous infusion of 0.2% ropivacaine for femoral never block was administrated at a rate of 5 ml/h for 48 hours to all patients.VAS scores and bending degree during rest,active and passive exer-cise were recorded at time point of postoperative 24,48,72,96 h.Ambulation status on the fifth day after operation were observed.Satisfaction of hospitalization were graded before hospital discharge. Results Compared with group FN,VAS scores during rest,active and passive excercise were signifi-cantly decrease at 24 h in group FNM (P <0.05 or P <0.01).The bending degree of knee joints in group FNM were significantly greater compared with group FN at 24 h after surgery (P <0.01).Am-bulation status on the fifth day after surgery were significantly better in group FNM compared with group FN (P <0.05).The level of patient satisfaction was much higher in group FNM (P <0.05). Conclusion After TKA,CFNB combined with single epidural morphine injection can provide better analgesia and bending degree with a high level of satisfaction.

A case of Streptococcus suis sepsis and streptococcal toxic shock syndrome diagnosed by metagenomic next-generation sequencing (mNGS) was presented. A 50-year old male patient visited Zengcheng Branch of Nanfang Hospital on June 25th, 2021. The patient developed fever, dizziness and shock with typical epidemiological history. mNGS revealed Streptococcus suis in blood sample. The diagnosis of Streptococcus suis sepsis and streptococcal toxic shock syndrome were made. Meropenem was given as empirical antibiotics. Antibiotics were adjusted to meropenem and clindamycin while Streptococcus suis was detecting by mNGS and downgraded to piperacillin/tazobactam and clindamycin when symptoms improved. The diagnosis was then confirmed by blood culture. The patient developed dry gangrene and sudden deafness in the later stage and was discharged after treatment. Compared with traditional diagnostic techniques, mNGS has advantages such as timeliness and accuracy, and plays a key role in the field of severe infections and rare pathogen infections. It is suggested that combining mNGS and traditional diagnostic techniques have the advantages for early diagnosis and early treatment.

0bjective To explore the effects of narrative nursing on posttraumatic growth for patients with amputation. Methods From December 2016 to March 2018,a total of 62 hospitalized patients with amputation were randomly assigned into the control group and the intervention group by random number table.The control group received routine nursing,the intervention group received narrative nursing on the basis of control group.Two groups were evaluated by Posttraumatic Growth Inventory(PTGI) before and after intervention. Results Before intervention,the scores of reflections on life, personal strengths, new possibilities, relating to others, self-transformation and posttraumatic growth in the the control group were (19.87 ± 5.22), (7.90 ± 2.53), (8.83 ± 3.62), (9.73 ± 3.13), (10.63 ± 3.01), (56.97 ± 17.21) points, respectively. After intervention,the scores were (20.80±5.89), (8.80±2.17), (8.90±3.39), (10.27± 2.75), (11.07 ± 3.12), (59.83 ± 16.91) points, respectively, except new possibilities, the scores of each dimension and total scores of posttraumatic growth in the the control group were higher than before,the differences were statistically significant(t=3.00- 5.34, P＜0.05).Before intervention,the scores of reflections on life, personal strengths, new possibilities, relating to others, self-transformation and posttraumatic growth in the the intervention group were (20.28±4.94), (8.17±2.58), (8.59±3.48), (9.55± 2.90), (11.07±2.83), (57.66±16.42) points, respectively. After intervention, the scores were (23.79±4.70), (10.10±2.17), (10.72±3.34), (11.69±2.22), (12.79±3.28),(69.10±14.92) points, respectively, the scores of each dimension and total scores of posttraumatic growth in the intervention group were statistically higher than those in the control group and before intervention,the differences were statistically significant (t=10.61-16.75, P＜0.05). Conclusion Narrative nursing can effectively improve the level of posttraumatic growth and psychological state for patients with amputation.
