Asthma is a chronic disease that affects the airways of your lungs. Your airways are the breathing tubes that carry air in and out of your lungs. When you have asthma, your airways become swollen
Inhaled beta-2 agonists raise heart rate, systolic blood pressure and contractility, all of which cause an increase in oxygen consumption of the heart. We performed a study on the influence of inhaled salbutamol on myocardial ischaemia, rhythm, and heart rate variability as assessed by Holter monitoring of 24 patients with coronary artery disease (CAD) and clinically stable asthma
Many patients admitted to an intensive care unit (ICU) will undergo a surgical procedure for correcting the underlying cause of their disease, to deal with the complications of their disease or the treatment of their disease, or to undergo diagnostic procedures which will direct the course of their treatment. The majority of these procedures are performed in the operating theatre, but a small …
The practice of anesthesiology includes provision of care to patients who are critically ill, while critical care medicine has its foundations in perioperative care provided by anesthesiologists, today’s critical care medicine encompasses care beyond traditional intraoperative and routine postoperative care. Critical care medicine includes a wide variety of clinical services provided by the a…
Fentanyl is one of the most widely used opioids for intravenous patient-controlled analgesia (IV-PCA). Sufentanil, a fentanyl analog, is suitable for postoperative pain control because it has no active metabolites and shows a higher therapeutic index and lower frequency of respiratory suppression than fentanyl. This study aimed to compare the two opioids for postoperative pain relief on the bas…
A double-blind study comparing four narcotic analgesics of different potencies, meperidine, morphine, fentanyl, and sufentanil, was performed on consenting patients undergoing general or orthopedic surgery under balanced anesthesia. Blood pressure, measured through an indwelling arterial catheter, was recorded continuously, as were ECG and heart rates. The narcotics, made up in equipotent conce…
We compared anesthetic doses of three popular opiates, morphine (n = 10), fentanyl (n = 9), and sufentanil (n = 9) in patients undergoing cardiac surgery. Opiate administration after induction was based upon EEG and cardiovascular signs of the depth of anesthesia. Total doses were morphine, 4.4 ± 0.71 mg/kg, fentanyl, 95.4 ± 9.9 μg/kg, and sufentanil, 18.9 ± 2.2 μg/kg.
This investigation was designed to compare the advantages and disadvantages of the older and less potent narcotics, morphine and meperidine, with fentanyl and sufentanil as components of balanced anesthesia
We studied 80 healthy ASA I patients (aged 20–52 yr) to determine if fentanyl affects sevoflurane requirements for achieving 50% probability of no movement in response to laryngoscopy and tracheal intubation (MAC-TI). Patients were allocated randomly to one of four fentanyl dose groups (0, 1, 2 and 4 g kg–1). Patients in each group received sevoflurane at a pre-selected end-tidal concentra…
