Effects of Transcutaneous Electrical Acupoint Stimulation on Stress Response during Intubation and Extubation in Patients Undergoing Video-Assisted Thoracoscopic Surgery: A Prospective, Randomized Controlled Trial.

OBJECTIVE: The study aimed to evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on the stress response during intubation and extubation in patients undergoing video-assisted thoracoscopic surgery (VATS). METHODS: 122 patients undergoing VATS lobectomy were randomly divided into two groups: the TEAS group (n = 62) and the control group (n = 60). Patients in the TEAS group underwent electroacupuncture stimulation of bilateral Neiguan (PC6), Hegu (L14), Lieque (LU7), and Chize (LU5) acupoints from 30 min before anesthesia to the end of surgery. The patients in the control group did not undergo stimulation. The primary endpoints were the hemodynamic parameters and plasma concentrations of epinephrine, norepinephrine, and cortisol. The secondary endpoints were the consumption of remifentanil and propofol, Ramsay sedation score and arousal time, extubation quality score, and postoperative complications. RESULTS: The hemodynamic variables and plasma concentrations of epinephrine, norepinephrine, and cortisol during intubation and extubation were lower in the TEAS group at T1, T3, and T4 compared with the control group. TEAS led to a reduction in the consumption of remifentanil (P < 0.01), as well as a reduction in the incidence of postoperative complications. The extubation quality score was lower (P < 0.01) while the Ramsay sedation score was higher (P < 0.01) in the TEAS group than in the control group. However, the arousal time and consumption of propofol were not significantly different between the two groups. CONCLUSION: TEAS can maintain hemodynamic stability, reduce the stress response during intubation and extubation, improve the quality of anesthesia recovery, and decrease the incidence of postoperative complications in patients undergoing VATS.

Ameliorative effect of berberine coated bio-active nanoparticles in acetaminophen induced hepato-renal damage in diabetic rats.

The current investigation was performed for the detailed analysis of protective effect of biofabricate berberine coated nano­silver ameliorate (BBR-AgNPs) on acetaminophen (APAP) induced hepato-renal damages in diabetic rats by blood biochemistry, tissue biochemistry, histopathological and immunohistochemical analysis. The spherical shaped BBR-AgNPs were synthesized by the Biofabrication technique and its physico-chemical characterizations done by different spectroscopic (UV-vis spectrophotometer, XRD spectroscopy, FTIR spectroscopy EDAX & DLS analyses) and microscopic (FE-SEM) techniques. The diabetic developed rats were administrated with APAP (2.0 g/5 mL/kg) and scrutinize its hepato-renal injuries. The synthesized BBR-AgNPs (75 mg/kg p.o) was administrated orally to the APAP-induced diabetic rats. The result of biochemical markers and lipid peroxidation were significantly (P ˂ 0.05) increased in APAP-induced diabetic rats but decreased the level of antioxidants (P ˂ 0.05), which results obtained in liver and kidney compared to the control group. Immunohistochemical studies result showed that the APAP-induced diabetic rats expressed a high immunoreactivity of nuclear transcription factor (NF-kB). Whereas, the acetaminophen-induced diabetic rats were treated with BBR-AgNPs renovated the changes in the above parameters analyzed. The results of the study clearly indicated that the BBR-AgNPs possess the antioxidant properties as well as anti-diabetic effects, furthermore, the acetaminophen-induced liver and kidney damage was probably inhibited by the inhibition of proinflammatory factor & NF-kB factors.
