Association of hemodynamics during caesarean section, outcomes after caesarean section and hormone changes with different anesthesia in pregnant women with severe pulmonary arterial hypertension.

In the present study we aimed to analyze the effects of different anesthesia methods on the hemodynamics of caesarean section, outcomes after caesarean section and hormone changes in pregnancy complicated with severe pulmonary arterial hypertension (PAH). A total of 75 pregnancy complicated with severe PAH that were treated in Jining First People's Hospital from January 2016 to January 2017 were selected. Three groups were set according to the anesthesia methods, including the subarachnoid combined epidural anesthesia group (group I, n=25), the epidural anesthesia group (group II, n=25) and the general anesthesia group (group III, n=25). Effects on the outcomes of caesarean section of pregnancy complicated with PAH were observed. Sex hormone levels before and 24, 48 and 72 h after the operation were measured. There were remarkable changes in the postoperative hemodynamics compared with those before anesthesia, but changes in groups I and II were significantly smaller than those in group III (P<0.05). No significant differences in maternal mortality rate, neonatal mortality rate and neonatal asphyxia rate among the three groups were found (P>0.05). Time of postoperative mechanical ventilation, ICU residence and hospitalization in groups I and II were shorter than those in group III, the differences were statistically significant (P<0.05). Postoperative levels of sex hormones, including estradiol (E2), human chorionic gonadotrophin (HCG), prolactin (PRL) and plasma total testosterone (TT) decreased, while postoperative levels of sex hormones follicle stimulating hormone (FSH), luteinizing hormone (LH) and progestogen increased, and differences in the decreased E2 and TT at each time-point were statistically significant (P<0.05). In conclusion, there is no remarkable difference in the effects of three anesthesia methods on pregnancy outcomes. However, compared with general anesthesia, intravertebral anesthesia achieve shorter time of postoperative mechanical ventilation, ICU residence and hospitalization in pregnancy complicated with severe PAH, which is preferred in pregnancy without contraindication of the anesthesia.

Effect of different anesthetic methods on cellular immune functioning and the prognosis of patients with ovarian cancer undergoing oophorectomy.

The present study aimed to explore the effects of different anesthetic methods on cellular immune function and prognosis of patients with ovarian cancer (OC) undergoing oophorectomy. A total of 167 patients who received general anesthesia (GA) treatment (GA group) and 154 patients who received combined general/epidural anesthesia (GEA) treatment (GEA group) were collected retrospectively. Each group selected 124 patients that met the inclusion and exclusion criteria for further study. ELISA and radioimmunoassay were employed to detect levels of IL-2, TNF-α, and CA-125. The rates of tumor-red cell rosette (RTRR), red cell immune complex rosette (RRICR), and red cell C3b receptor rosette (RRCR) were also measured. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were determined by hemodynamics. The levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-2 decreased at 1 h intraoperation (T2), but increased 24-h post surgery (T3). The levels of TNF-α and IL-2 were recovered faster in the GEA group than in the GA group. The GA group exhibited greater levels of CA-125 expression than in the GEA group. The levels of RTRR, RRICR, and RRCR; ratios of CD3+, CD4+, CD4+/CD8+, CD16+, and CD56+ at 30 min after anesthesia (T1), T2, T3 and 48 h after the operation (T4) and levels of SBP, DBP, and HR at T1, T2, and T3 displayed increased levels in the GEA group than in the GA group. At 72-h post surgery (T5), the 5-year survival rate significantly increased in the GEA group compared with the GA group. GEA to be more suitable than GA for surgery on OC patients.

Effects of different anesthesia methods on postoperative transient neurological syndrome in patients with lumbar disc herniation.

The objective of the present study was to investigate the effects of different anesthesia methods on postoperative transient neurologic syndrome (TNS) in patients with lumbar disc herniation (LDH). Ninety-six patients with LDH were selected from November 2015 to October 2016 in Cangzhou Central hospital. All patients were treated with percutaneous transforaminal endoscopic discectomy. The patients were randomly divided into the control group and observation group, with 48 patients each. Combined spinal-epidural anesthesia was performed for patients in the control group, while epidural anesthesia was applied in the observation group. The levels of T lymphocyte subsets (CD4+ and CD8+) and inflammatory factors (IL-2 and TNF-α) were measured and compared before and 1 week after surgery. The incidence rate of TNS within 1 week after surgery was compared between the two groups. Fugl-Meyer Assessment was used to evaluate lower limb motor function and sensory disturbances at 1, 3 and 5 days after treatment. One week after treatment, the serum levels of CD4+ and CD8+ in the two groups were significantly lower than those before surgery (p<0.05), but no significant differences were found between the groups (p>0.05). The incidence rate of TNS within 1 week after surgery was significantly lower in the observation group than in the control group (p<0.05). The scores of lower limb motor function and sensory disturbances in the observation group evaluated at 1, 3 and 5 days after treatment were significantly higher than those in the control group (p<0.05). In conclusion, combined spinal-epidural anesthesia and epidural anesthesia caused no significant differences in immune function or inflammatory indexes in patients with LDH. However, the application of epidural anesthesia significantly reduced the incidence rate of postoperative TNS, which in turn reduced nerve damage.

Effect of 2 different anesthesia methods on stress response in neurosurgical patients with hypertension or normal: A prospective clinical trial.

Hypertensive patients in neurosurgery are becoming more common, which increased the risk of surgical stress response. Meanwhile, the relationship between hypertension and anesthesia methods is unclear on the stress response. The purpose of this study is to compare the effect of different anesthesia methods on high-sensitivity C-reactive protein (Hs-CRP), blood glucose, and leucocyte levels in neurosurgical patients with hypertension or normal.Eighty neurosurgical patients were randomly divided into 4 groups (n = 20): balanced anesthesia group (A), balanced anesthesia with hypertension group (B), total intravenous anesthesia group (C), total intravenous anesthesia with hypertension group (D). The levels of Hs-CRP, blood glucose, leucocyte count, and neutrophil percentage and were detected at before anesthesia (T0), during anesthesia (T1), 2 hours post anesthesia (T2), 24 hours post anesthesia (T3).Patients with hypertension had higher Hs-CRP expression, blood glucose, and neutrophil percentage at time T0 than those of normal, but not leucocyte count. At time T3, patients with hypertension in D group had lower Hs-CRP expression than those in B group (P < 0.01). Patients with normal in C group had lower Hs-CRP expression (P < 0.01), blood glucose (P < 0.05), and leukocyte count (P < 0.05) than those in A group. Both hypertension history and anesthesia method had significant effects on the Hs-CRP expression, blood glucose, and leukocyte count.Total intravenous anesthesia decreases Hs-CRP expressions more efficiently than balanced anesthesia in neurosurgical patients with hypertension or normal. Moreover, total intravenous anesthesia can availably reduce the perioperative stress response by attenuating the increase of blood glucose and leukocyte count in normal tensive patients.

Effects of Different Anesthetic Methods on Cellular Immune and Neuroendocrine Functions in Patients With Hepatocellular Carcinoma Before and After Surgery.

Many anesthesia methods have been studies in hepatocellular carcinoma (HCC). We aimed to explore the effects of combined intravenous and inhalation anesthesia and combined general and epidural anesthesia on cellular immune function and neuroendocrine function in patients with HCC before and after surgery. Between September 2012 and April 2014, 72 patients who underwent a hepatectomy in our hospital were enrolled. Compared with the combined intravenous and inhalation anesthesia group, the combined general and epidural anesthesia group demonstrated increased CD4+ /CD8+ T cells 0 hr after surgery, increased CD3+ , CD4+ , CD4+ /CD8+ cells, and IFN-γ levels 12 hr after surgery, and increased CD3+ , CD4+ , and CD4+ /CD8+ cells 24 hr after surgery (all P < 0.05). At 72 hr after surgery, the levels of ACTH and Cor in the combined general and epidural anesthesia group, and the levels of CD3+ , CD4+ , CD4+ /CD8+ cells, and IFN-γ in both the combined intravenous and inhalation anesthesia and the combined general and epidural anesthesia groups decreased to pre-surgery levels. Significant differences were observed in the comparisons of CD3+ , IL-6, and IL-10 between the combined intravenous and inhalation anesthesia and the combined general and epidural anesthesia groups 72 hr after surgery (all P < 0.05). Our results revealed that combined general and epidural anesthesia plays a crucial role in hepatectomy via the mitigation of the inhibition of immunologic function in HCC patients during the perioperative period. Combined general and epidural anesthesia also hastens the recovery of immunologic suppression after surgery, which can provide a certain reference for the selection of clinical anesthesia in the treatment of HCC.

The effects of different anesthetic methods on neuronal activity and movement symptoms of Parkinson’s disease

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is widely used in the treatment of Parkinson’s disease. DBS surgery is usually performed with the patient under local anesthesia (LA). However, a number of patients do not tolerate LA due to anxiety or severe pain. These patients require surgery under sedation or general anesthesia. Unfortunately, anesthetic drugs interfere with the intraoperative microelectrode recordings. A debate regarding the usefulness of sedation or general anesthesia during DBS surgery is still in progress. In this study, we evaluated whether the differences in anesthetic methods affect STN single-unit activity and movement symptoms of Parkinson’s disease. Eight patients underwent surgery to implant bilateral STN DBS electrodes. Our study compares STN single-unit activity under both LA and monitored anesthesia care (MAC) in the same patients as well as movement symptoms of Parkinson’s disease. The primary results revealed no significant difference in the mean firing rate of STN single-unit activity under LA and MAC. However, there were differences in the spike characteristics and firing patterns of STN activity between the two anesthetic methods. These findings contribute valuable insight into the effects of different anesthetic methods on STN single-unit activity for precise electrode localization during DBS surgery.

Effect of different anesthesia methods on erythrocyte immune function in mice

ObjectiveTo explore effect of different anesthesia methods and different anesthetics on erythrocyte immune function in mice. MethodsThe mice were anesthetized by isoflurane and ether inhalation, and also under intraperitoneal anesthesia with sodium pentobarbital and chloral hydrate. Blood was collected from the ventro-cardinal vein. Automatic blood cell analyzer was used for routine blood examination, and the canthine oxidase method was used to measure the superoxide dismutase (SOD) activity. Lipid peroxidation product malondialdehyde (MDA) was measured with TBA, and glutathione peroxidase (GSH-Px) was measured with DTNB, and then the effect of different anesthesia methods and different anesthetics on erythrocyte immune function in mice was observed. ResultsHct level of chloral hydrate intraperitoneal injection group was significantly higher than the other three groups (P<0.05). And the MDA levels in the pentobarbital sodium group were significantly higher than the other three groups (P<0.05). SOD and GSH-Px of the chloral hydrate and sodium pentobarbital intraperitoneal injection group were significantly lower than the other two groups; RBC-C 3bRR and RBC-ICR of the chloral hydrate and sodium pentobarbital intraperitoneal injection group were significantly lower than the other two groups. ConclusionsDifferent drugs can induce changes in immune function of mice at different levels. Isoflurane and ether have less damage to animal body, while chloral hydrate and sodium pentobarbital intraperitoneal injection have a certain inhibitory effect on the animal body respiratory system and can cause greater damage to the body. Therefore, the reasonable selection and control of anesthetics are very important in order to avoid the experimental errors caused by anesthesia.
