Although the acute increase of arterial stiffness and blood pressure (BP) after cigarette smoking in healthy smokers is considered a possible mechanism increased cardiovascular risk, effect on hypertensive unknown. We investigated effects BP male smokers. Heart rate (HR), brachial ankle BP, pulse-wave velocity (PWV) were measured 22 (HTs) 30 normotensive (NTs) before 5, 10, 15 min one (nicotine content, 0.9 mg). Smoking induced increases HR, heart–femoral PWV (hfPWV) NTs HTs (P < .05). Ankle...
Diaphragmatic dysfunction is a major factor in the etiology of postoperative pulmonary complications after upper abdominal surgery. M-mode ultrasonography now an accepted qualitative method assessing diaphragmatic motion normal and pathological conditions. In this study, we evaluated whether inspiratory amplitude (DIA) as measured by sonography can be predictor dysfunction.A prospective, single-center, single-unit, observational study was performed 35 ASA physical status I II nonsmoking...
Postoperative pressure ulcers are important indicators of perioperative care quality, and serious expensive complications during critical care. This study aimed to identify risk factors for postoperative ulcers.This retrospective case-control evaluated 2,498 patients who underwent major surgery. Forty-three developed were matched 86 control based on age, sex, surgery, comorbidities.The ulcer group had lower baseline hemoglobin albumin levels, compared the group. The also higher values...
Total laparoscopic hysterectomy (TLH) has become a widely accepted alternative to total abdominal (TAH). The aim of this study was compare the incidence and grade venous air embolism (VAE) in TLH those TAH using transesophageal echocardiography.Eighty-two American Society Anesthesiologists physical status I patients scheduled for either or were enrolled. After induction general anesthesia, multiplane echocardiography probe inserted. midesophageal four-chamber bicaval view continuously...
To examine the impact of implementing sepsis bundle in multiple Asian countries, having 'team' vs. 'non-team' models patient care. Prospective cohort study. Eight urban hospitals, five countries Asia. Adult patients with severe or septic shock. Implementation was divided into six quartiles: Baseline, Education and four Quality Improvement quartiles. Quarterly compliance in-hospital mortality respect to completion implementation model. In team model, championed by intensivists, where...
Anaesthesia is required for catheter ablation of atrial fibrillation (A-fib) to achieve patient comfort and immobilization avoid map shifts. This study compared the analgesic sedative efficacies dexmedetomidine–remifentanil with those midazolam–remifentanil A-fib. Ninety patients were randomized receive either intermittent midazolam boluses (1–2 mg) 3.6–7.2 µg/kg/h remifentanil (MR group) or dexmedetomidine 0.2–0.7 after a loading dose 1 µg/kg 1.2–2.4 (DR group). The sedation level assessed...
It has been recognized that the sympathetic nervous system is activated in pulmonary arterial hypertension (PAH), and abnormal hyperactivity leads to worsening of PAH via endothelial dysfunction. The purpose this study was examine whether ganglion block (SGB) can treat by increasing availability nitric oxide (NO). induced rats 50 mg/kg subcutaneous monocrotaline. After 2 weeks, daily injections ropivacaine into left superior cervical were repeated for 14 days (monocrotaline-SGB group)....
The objective of this study was to establish the efficacy and safety procalcitonin (PCT)-guided antibiotic discontinuation in critically ill patients with sepsis a country high prevalence antimicrobial resistance national health insurance system.In multi-center randomized controlled trial, were randomly assigned PCT group (stopping antibiotics based on predefined cut-off range PCT) or control group. primary end-point duration. We also performed cost-minimization analysis PCT-guided...
Intraoperative transesophageal echocardiography has become a routine part of monitoring in patients with cardiac disease. However, insertion probe can be associated oropharyngeal, esophageal, and gastric injuries. The purpose this study was to determine whether under direct laryngoscopic visualization reduce the incidence oropharyngeal mucosal injury.Eighty undergoing surgery general anesthesia were randomly allocated either conventional group, which inserted blindly, or laryngoscope rigid...
Continuous renal replacement therapy (CRRT) has been widely used in critically ill acute kidney injury (AKI) patients. Moreover, some centers operate a specialized CRRT team (SCT) composed of physicians and nurses, but few studies have yet determined the superiority SCT control.A total 334 among 534 patients original cohort, who started for severe AKI between August 2007 September 2009 Yonsei University Health System were matched with propensity score (PS), divided into two groups based on...
Purpose: This study aimed to investigate the effects of patient-directed interactive music on saliva melatonin levels and sleep quality among postoperative elderly patients in intensive care unit (ICU). Patients Methods: A total 133 were randomized into three groups: therapy (IMT), passive listening (PL), control group. The group (n = 45) received routine medical care, while IMT PL groups ICU day 1. up 20 mins sessions, including relaxation techniques. only pre-selected relaxing...
Predicting fluid responsiveness in patients under mechanical ventilation with low tidal volume (VT) is challenging. This study evaluated the ability of carotid corrected flow time (FTc) assessed by ultrasound for predicting during VT ventilation. Patients postoperative and clinically diagnosed hypovolemia were enrolled. Carotid FTc pulse pressure variation (PPV) measured at 6 10 mL/kg predicted body weight (PBW). was calculated using both Bazett’s (FTcB) Wodey’s (FTcW) formulas. Fluid...
This study was performed to test if hearing a recorded maternal voice reduces anxiety, emergence agitation and anaesthetic requirements in children. With written informed consent, children scheduled for cardiac catheterisation under intravenous ketamine anaesthesia their mothers (n=46) were randomly assigned either the mother-voice (MV) or control group. While MV group (n=23) listened via headphones recording of mothers’ voices during perioperative period, wore with no auditory stimulation....
Contrast medium used for radiologic tests can decrease renal function. However there have been few studies on contrast-associated acute kidney injury in intensive care unit (ICU) patients. The objective of this study was to evaluate the incidence, characteristics, and outcome (CA-AKI) patients using Risk, Injury, Failure, Loss, End-stage disease (RIFLE) criteria critically ill ICU.We conducted a retrospective adult who underwent contrast-enhanced from January 2011 December 2012 30-bed...
Dexmedetomidine is a commonly used sedative and adjuvant agent to general anesthesia. The present was designed evaluate the effects of dexmedetomidine on myocardial function by using tissue Doppler echocardiography during anesthesia in patients with diastolic dysfunction. Forty undergoing orthostatic surgery ejection fraction preserved dysfunction grade 2 or 3 were randomly allocated Control Dex group (n = 20, each). In group, given as an initial loading dose 1.0 μg/kg over 10 minutes...
