ABSTRACT
Objective:To investigate the effect of ultrasound-guided early removal of indwelling catheter on recovery quality and catheter-related infection of patients with general anesthesia in post anesthesia recovery unit (PACU).Methods:From September 2019 to April 2020, 146 patients with gynecological benign diseases who underwent hysteroscopic surgery in the Department of Anesthesiology, Shenzhen Hospital of Southern Medical University were selected prospectively and randomly divided into two groups, with 4 cases excluded. The function of the bladder was evaluated by ultrasound in the anesthesia recovery room after operation. In the ultrasound group, 71 patients had no abnormality, and the catheter was removed after the residual urine of the bladder was drained. 71 patients in the control group were normal, and the catheter was removed 24 hours after operation. The residual urine volume, urine retention, incidence of restlessness, urinary tract infection rate, time to first walking and hospital stay were observed in the two groups after the first bladder emptying.Results:The incidence of agitation in PACU was 7.0%(5/71) in the ultrasound group and 22.5%(16/71) in the control group, with statistically significant difference ( P<0.01); the first postoperative walking time in the ultrasound group and the control group was statistically significant [(10.5±4.1)h vs (18.9±6.5)h, P<0.05]; the postoperative hospital stay in the ultrasound group and the control group was statistically significant [(3.2±1.3)d vs (5.1±2.5)d, P<0.05]. The incidence of urinary tract infection and urinary tract irritationin in ultrasound group was significantly lower than that in control group (1.4% vs 9.8%, 1.4% vs 14.0%, P<0.05). Conclusions:For uncomplicated patients after gynecological laparoscopic surgery, ultrasound evaluation of bladder function, extraction of residual urine immediately after the removal of catheter, is more conducive to the early recovery of patients than 24 hours after the removal of catheter.
ABSTRACT
OBJECTIVE@#To examine the expression of HIF-1alpha and CD34 in nasopharyngeal carcinoma and nasopharyngitis tissues, evaluate the role of HIF-1alpha and microvessel density (MVD) in nasopharyngeal carcinoma, probe the relationship between HIF-1alpha and MVD.@*METHOD@#The expression of HIF-1alpha was detected in 58 cases with nasopharyngeal carcinoma and 20 samples of nasopharyngitis tissues by immunohistochemical staining SABC methods and SP methods. MVD in tumor was counted by immunostaining with CD34 and analyzed with clinicopathologic parameters.@*RESULT@#The positive rate of HIF-1alpha was 79.31% and 10.00% respectively in nasopharyngeal carcinoma and nasopharyngitis tissues, there was significant difference between them (P<0.01). MVD was 39.74+/-7.41 and 18.43+/-3.24 respectively in nasopharyngeal carcinoma and nasopharyngitis tissues, there was significant difference between them (P<0.01). The expression of HIF-1alpha and MVD were significantly higher in nasopharyngeal carcinoma and in lymph node metastasis group than in no-metastasis group. In different clinical stage, the expression of HIF-1alpha (P<0.05) and MVD (P<0.01) was different. The expression of HIF-1alpha was positively correlated with MVD (P<0.01).@*CONCLUSION@#HIF-1alpha may be involved in carcinogenesis, invasion and metastasis of NPC. Visualization plays a key role in invasion and metastasis of NPC. The expression of HIF-1alpha was positively correlated with tumor visualization in NPC. HIF-1alpha is likely to be a potential target of anticancer therapy.
