Music's use for anesthesia and analgesia.

This review article provides an overview of published data regarding the involvement of music in anesthesia practice. Music is an important topic for research in different fields of anesthesiology. The use of music preoperatively is aimed at reducing anxiety, stress, and fear. However, the effect of music on perception of pain intraoperatively is controversial, according to studies of both adults and children undergoing various surgical procedures under general and/or regional anesthesia. In postoperative pain management, postanesthesia care, and neonatal intensive care, music can be a complementary method for reducing pain, anxiety, and stress. Music is a mild anxiolytic, but it is relatively ineffective when a pain stimulus is severe. However, music is inexpensive, easily administered, and free of adverse effects, and as such, can serve as complementary method for treating perioperative stress and for acute and chronic pain management, even though music's effectiveness depends on each individual patient's disposition and severity of pain stimulus.

Greek surgical patients' satisfaction related to perioperative anesthetic services in an academic institute.

BACKGROUND: Patient satisfaction is an increasingly appreciated measure of outcome for health care procedures. The purpose of this study was to evaluate Greek surgical patients' satisfaction with perioperative anesthetic services and to determine which factors maximize satisfaction level through all phases of perioperative care. METHODS: Adult Greek patients admitted for elective surgery in an academic hospital were included in the study. Three separate questionnaires were constructed: Q1 (patients who underwent general anesthesia alone or combined with epidural) and Q2 (patients who received regional anesthesia alone) covered perioperative anesthetic care; Q3 covered postoperative analgesia services in the ward (patient-controlled analgesia or epidural analgesia) provided by our anesthesiologist-centered analgesia care team. Principal component analysis with varimax rotation was used separately for each questionnaire, and extracted factors were entered into multiple logistic regression with patient satisfaction as the dependent binary variable. Statistical significance level was set at P < 0.05. RESULTS: Three hundred and forty-five patients were included. Q1 questionnaire (answered by 282 patients) included four dimensions: communication with the anesthesiologist, sense of cold/shivering, pain, and nausea. Q2 questionnaire (answered by 63 patients) included three dimensions: communication with the anesthesiologist, sense of cold/shivering, and nausea/anxiety. Q3 questionnaire (answered by 237 patients) included five dimensions: anesthesiologist intervention upon symptoms, pain, care by the anesthesiologist/physical activity, nausea/vomiting, and anesthesiologist behavior. The communication dimension score in Q1 and Q2, sense of shivering in Q2, and pain management and anesthesiologist behavior dimension scores in Q3 were significantly associated with patient satisfaction. Overall satisfaction rates were high (according to the questionnaire, the observed percentage was in the range of 96.3%-98.6%). CONCLUSION: Greek surgical patients reported high satisfaction with perioperative anesthesia care. Interaction between patient and anesthesiologists during all periods of study, absence of shivering in regional anesthesia, and adequate postoperative pain control in the ward were significant predictors of patient satisfaction in the present Greek surgical population.

Low-dose (1 microg/kg) clonidine premedication and hypotension after carotid artery surgery.

We investigated the role of low-dose clonidine intravenous (IV) premedication in arterial pressure variation during and after carotid endarterectomy (CEA). A total of 84 patients, American Society of Anesthesiologists (ASA) II-III, scheduled for elective CEA under general anesthesia participated in this study. The patients were divided into 2 groups: group P (n = 42) and group C (n = 42) and received N/S 0.9% (placebo) or clonidine 1 µg/kg IV, respectively, 15 minutes before induction of anesthesia. Recovery times, number of patients needed to be treated for circulatory events (hypertension, hypotension, and bradycardia), number of circulatory events per patient, and consumption of vasoactive drugs (nitroglycerine, phenylphrine, and atropine) intraoperatively and the first 6 hours postoperatively were recorded. Significantly less hypertensive episodes were observed intraoperatively, but more hypotensive episodes were observed postoperatively in patients receiving clonidine. Intravenous premedication with low-dose clonidine (1 µg/kg) seems to be effective in preventing hypertensive episodes during CEA under general anesthesia but seems to increase the incidence of hypotension postoperatively.

Epidural haematoma after epidural catheter removal under multiple anticoagulant therapy: report of two cases.

We report two cases of epidural haematoma that probably developed after removal of the epidural catheter in patients receiving multiple anticoagulant and antiplatelet therapy. The first case is a 77-year-old male patient who underwent femoropopliteal artery bypass grafting surgery. The second case is a 77-year-old woman who underwent a semi-total replacement of the right hip, three days after she had a subtrochanteric fracture. Emergency laminectomy was performed in both patients but none experienced a full recovery.
