“…We suggest that a lower mean LF/HF ratio and a low number of patients with LF/DF of >2.5 in our study was the reason for the difference from other studies. Our findings were similar to those of Meyhoff et al (35), who found no difference in the incidence of spinal anesthesia-induced hypotension in patients with LF/ HF above or below 2.5 (6 patients among 9 and 9 patients among 15, respectively). The principal goal of this study was to evaluate the effect of spinal anesthesia on HRV, not to use HRV as a prognostic tool.…”

Molecular Electric Multipole Moment (MEMM) integrals have been derived for diatomic molecular systems, and then some lower multipole moments as dipole moments and quadrupole moments have been calculated for some diatomic molecules. The calculations have been performed by using our analytical formula over Slater-Type orbitals (STOs) with Cade and Huo's basis sets and the GAMESS program package working with Gaussian-Type basis sets (GTOs). The expressions which involve factorials are given in terms of binomial coefficients in order to speed up calculations. The results have been obtained in agreement with data found in the literature.

“…A significant factor for the development of hypotension is the age of the anaesthetized patients. Higher incidences of hypotension are observed in the elderly, i.e., 70−75% [20,22]. In our population, the patients were under 60 years of age, and the age-related risk was irrelevant.…”

Background: Unfavourable circulatory system conditions have been observed in many patients with spinal anaesthesia. The most frequent symptoms include a decrease in blood pressure and, less frequently, bradycardia. The appearance of unfavourable consequences of spinal anaesthesia might be related to the initial status of the patient's circulatory system. The aim of this study was to establish the possibility of predicting unfavourable circulatory consequences (hypotension, bradycardia) following spinal anaesthesia, based on non-invasive haemodynamic assessment with a Nexfin device. Methods: This prospective study included 100 18-60-year-old ASA I or II planned spinal anaesthesia patients. The initial hemodynamic parameters were assessed with a Nexfin monitor. Anaesthesia was performed with 3−3.5 mL of a 0,5% hyperbaric bupivacaine solution. Within 20 min after the administration of anaesthesia, the arterial blood pressure values, heart rate, sensory blockade level, and motoric blockade level were recorded in 5-min intervals. Hypotension was classified by a decrease of SAP < 90 mm Hg and/or the decrease of the SAP ≥ 20% initial value. Logistic regression was used to determine the independent predictors of hypotension resulting from a spinal blockade. Results: The development of hypotension and bradycardia was observed in 39 and 2%, respectively, of the patients. The patients who developed hypotension differed significantly from those who did not develop this symptom, with the main difference being the body mass and the assessment on the ASA scale. The patients who developed hypotension after spinal anaesthesia differed significantly in the initial hemodynamic parameters (SAP, MAP, SVRI). The following two independent risk factors for hypotension were isolated: the mean arterial pressure (OR 1.04; 95% CI: 1.005-1.076) and the systemic vascular resistance index (OR 1.109; 95% CI: 1.021-1.204). Conclusions: Nexfin-based non-invasive haemodynamic monitoring might be helpful in the identification of individuals with a high risk of hypotension following spinal blockade.

“…1 It is more common in elderly patients, with a reported incidence of 65-75%. [2][3][4] In addition, hypotension during spinal anesthesia may be combined with bradycardia-caused by the blockade of sympathetic cardiac accelerator fibers that arise at T1-T4-to prevent the development of reflex tachycardia. 5 Hemodynamic changes induced by spinal anesthesia can be deleterious in elderly patients with decreased cardiovascular reserve and other comorbidities due to the risk of organ ischemia.…”
