ABSTRACT
Objective@#To investigate the effects of remifentanil combined with propofol on hemodynamics, inflammatory stress response and immune function in patients with acute abdomen complicated with septic shock.@*Methods@#From June 2017 to August 2018, 112 patients with acute abdomen complicated with septic shock who admitted to the First Affiliated Hospital of Xiamen University were enrolled in the study.They were randomly divided into observation group and control group according to the digital table, with 56 cases in each group.The control group was anesthetized with sevoflurane combined with propofol.The observation group was anesthetized with remifentanil combined with propofol.The hemodynamic parameters of the patients entering the operating room(T0), 0.5h(T1), 1h(T2) and awake(T3) after anesthesia were recorded.The intraoperative norepinephrine dosage was recorded.The inflammatory response, stress response and immune function indicators at T0, T2 and T3 were recorded.@*Results@#Compared with T0, T1 and T2, the MAP of the two groups was higher at T3, and the differences were statistically significant(tcontrol group=4.834, 4.484, 5.378, tobservation group=6.420, 7.006, 6.152, all P<0.05). Compared with T0, the HR of the two groups was higher at T3, and the differences were statistically significant(tcontrol group=5.943, tobservation group=7.722, all P<0.05). Compared with T1 and T2, CO of the two groups was higher at T3, and the differences were statistically significant(tcontrol group=4.276, 2.262, tobservation group=6.318, 5.132, all P<0.05). There were no statistically significant differences in MAP, HR and CO between the two groups at T0, T1, T2 and T3(all P>0.05). The doses of norepinephrine in the observation group and the control group were (1 587.7±287.5)μg and (1 937.9±397.6)μg, respectively, and the difference was statistically significant(t=5.341, P<0.05). The serum levels of C reactive protein(CRP), tumor necrosis factor alpha(TNF-α) and interleukin 6(IL-6) increased with time in the two groups, and the differences were statistically significant(tcontrol group=17.06, 36.13, 19.07, 3.822, 9.466, 2.874, 14.18, 26.87, 16.21, tobservation group=11.72, 20.79, 11.01, 2.810, 6.559, 3.716, 10.52, 24.56, 17.64, all P<0.05). At T2 and T3, the serum levels of CRP, TNF-α and IL-6 in the observation group[T2: CRP (89.63±17.65)mg/L, TNF-α (51.16±10.16)ng/L, IL-6 (34.26±6.25)ng/L, T3: CRP (136.15±26.25)mg/L, TNF-α (58.64±11.12)ng/L, IL-6 (67.56±12.67)ng/L]were lower than those in the control group[T2: CRP (112.15±22.34)mg/L, TNF-α (59.56±11.58)ng/L, IL-6 (42.65±8.37)ng/L, T3: CRP (175.16±34.75)mg/L, TNF-α (65.79±11.35)ng/L, IL-6 (79.02±14.56)ng/L], the differences were statistically significant(t=5.919, 6.703, 4.080, 3.367, 6.010, 4.443, all P<0.05). Compared with T0, serum levels of epinephrine(E), cortisol(Cor) increased in two groups at T2 and T3, and the differences were statistically significant(tcontrol group=10.03, 8.096, 8.679, 7.029, tobservation group=6.473, 4.728, 6.330, 4.727, all P<0.05). Compared with T2, serum levels of E and Cor in two groups at T3 were decreased, and the differences were statistically significant(tcontrol group=2.400, 2.638, tobservation group=2.260, 2.162, all P<0.05). At T2 and T3, the serum levels of E, Cor in the observation group[T2: E (286.36±41.02)ng/L, Cor (262.52±29.89)μg/L, T3: E (270.35±33.59)ng/L, Cor (253.23±30.28)μg/L]were lower than those in the control group[T2: E (312.56±38.75)ng/L, Cor (287.56±38.76)μg/L, T3: E (295.79±35.12)ng/L, Cor (270.25±30.15)μg/L], the differences were statistically significant (t=3.457, 3.917, 3.828, 2.981, all P<0.05).

ABSTRACT
Objective To evaluate the efficacy of the thoracic approach to thoracic paravertebral blockade ( PVB) performed via video-assisted thoracoscope on postoperative analgesia in patients undergoing lobectomy. Methods A total of 84 patients of both sexes, aged 44-64 yr, with body mass index of 19. 7-24. 9 kg∕m2 , of American Society of Anesthesiologists physical statusⅡorⅢ, scheduled for elective vide-o-assisted thoracoscopic unilateral lobectomy, were divided into 2 groups ( n=42 each) using a random number table method: thoracic PVB group (TP group) and control group (C group). In TP group, the thoracic approach to thoracic PVB was performed on the affected side via video-assisted thoracoscope before closing the chest, and 0. 375％ ropivacaine hydrochloride 20 ml was injected. Then patient-controlled intra-venous analgesia ( PCIA) was performed in both groups. PCIA solution contained dezocine 0. 6 mg∕kg, flurbiprofen axetil 200 mg, palonosetron 0. 5 mg and dexamethasone 10 mg in 120 ml of normal saline. The PCA pump was set up with a 0. 5 ml bolus dose, a 15 min lockout interval and background infusion at a rate of 2 ml∕h after a loading dose of 5 ml. Duration of operation was recorded. The peak expiratory flow rate ( PEFR) was recorded before surgery and at 6, 24 and 48 h after surgery. The amount of dezocine and pressing times of PCA were recorded at 24 and 48 h after surgery. The occurrence of drowsiness, dizziness, nausea and vomiting was recorded after surgery. Tramadol 2 mg∕kg was intravenously injected as rescue an-algesic when visual analog scale score≥4 points. Results Compared with group C, the amount of dezo-cine and pressing times of PCA were significantly reduced at 24 and 48 h after surgery, the requirement for rescue analgesia and incidence of nausea and vomiting were decreased, and the PEFR was increased at 6 h after operation in group TP ( P<0. 05) . Conclusion The thoracic approach to PVB performed via video-assisted thoracoscope can enhance the efficacy of postoperative analgesia in patients undergoing lobectomy.
