The effects of different degrees of head-of-bed elevation on the respiratory pattern and drainage following thyroidectomy: a randomized controlled trial.

BACKGROUND: The patient's position is important for ensuring patient comfort and preventing complications after thyroidectomy. OBJECTIVES: This study was carried out to determine the effects of different degrees of head-of-bed elevation (HOBE) on the respiratory pattern and drainage following thyroidectomy and to provide suggestions for evidence-based clinical practice. METHODS: The sample of this prospective, parallel arm, randomized controlled trial included 114 patients undergoing thyroidectomy in a university hospital in Turkey. The patients were randomly assigned (1:1:1) to supine 0° (baseline), 30° and 45° HOBE groups. Respiratory pattern including respiratory rate (RR), peripheral oxygen saturation (SpO2) and dyspnea, and drainage including amount of drainage and hematoma formation were evaluated at the 1rd, 2rd, 3rd and 4th hours following thyroidectomy. RESULTS: The majority of the patients (83.3%) were female and 84.2% had undergone total thyroidectomy. The mean RR (18.47, 95% CI=17.85-19.09) of the patients in the supine 30° HOBE group at the 1rd hour was significantly higher than that of the patients in the supine 0° group (17.32, 95% CI=16.88-17.76; p<0.05). There was no significant difference between the SpO2 values of the patients in the groups (p>0.05). The amount of drainage was significantly higher in the supine 0° group at the 2nd hour than that of the patients in the supine 45° HOBE group (5.92±5.18; 3.34±5.56 respectively; p<0.05). None of the patients in the groups had hematoma formation. While no patient in the supine 30° HOBE group had dyspnea, dyspnea occurred in 9 patients in the supine 0° group and in 3 patients in the supine 45° HOBE group. CONCLUSION: This study showed that different HOBE positions resulted in clinically insignificant changes on the RR and amount of drainage during the first 4 hours following thyroidectomy but did not affect SpO2 value.

Japanese nurses' perception of their preparedness for disasters: Quantitative survey research on one prefecture in Japan.

AIM: The objective of this study was to explore nurses' perceptions regarding their knowledge, skills, and preparedness for disasters and how they acquired their knowledge about disaster preparation using a quantitative approach. METHODS: A descriptive cross-sectional survey using the Disaster Preparedness Evaluation Tool was distributed to nurses in six hospitals (three private, three public) throughout Miyazaki Prefecture located in southern Japan. RESULTS: Nine hundred and seventy-three surveys (87.4%) were returned. Seventy-two were eliminated leaving 902 (81.0%) for data analysis. Mean scores for preparedness, response abilities, and evaluation all scored below normal on a 6 point Likert scale (2.63, 2.02, and 2.05, respectively). Overall, nurses felt they were not able to respond in a variety of disaster situations, were aware of their workplace emergency disaster plan, but did not think they could execute them, and were not aware of the level of preparedness of the healthcare systems in their communities. CONCLUSION: The amount of information nurses need to know on the knowledge, skills, and preparation of disasters are in great need. Such skills are understood, but lacking for various reasons. In-house programs for nurses to learn more about disaster nursing are needed. Furthermore, a curriculum for disaster preparedness for undergraduate and graduate nursing programs would also help these future nurses gain more information earlier on to better prepare them for possible disaster situations in their future careers.

The pharmacological protection of renal function in patients undergoing cardiac surgery.

OBJECTIVES: To compare the effects of different routes and timings of administration of dopamine and mannitol used to alleviate the adverse effects of prolonged cardiopulmonary bypass (CPB) on renal functions in coronary artery surgery. METHODS: Group I (n: 25 patients): Mannitol 1 g/kg was added into the priming solution for CPB. Group II (n: 25 patients): IV dopamine was administered at a dose of 2 µg/kg/min during the time period between anesthesia induction and end of surgery. Group III (n: 25 patients): IV dopamine was administered at a dose of 2 µg/kg/min during the time period between anesthesia induction and end of surgery and mannitol 1 g/kg was added into the priming solution for CPB. Group IV (n: 25 patients) (Controls): Furosemide was given when the urine output was low. RESULTS: There was a significant increase in post operative urine microalbumin/creatinine ratio in all groups (p < 0.05), even increase of cystatin-c in Groups I, II and III (p < 0.01). CONCLUSIONS: We believe that concurrent use of dopamine infusion (2 µg/kg/min) with mannitol (1 g/kg) during CPB may represent a more effective strategy for the prevention of the untoward effects of CPB on renal functions.

Sugammadex Use in a Patient with Wolff-Parkinson-White (WPW) Syndrome.

BACKGROUND: Wolff-Parkinson-White (WPW) syndrome is a disease associated with episodes of supraventricular tachycardia and ventricular pre-excitation or atrial fibrillation. WPW is characterized by an aberrant electrical conduction pathway between atria and ventricles. CASE REPORT: The major anesthetic problem connected with WPW syndrome is the risk of tachyarrhythmias due to accessory pathway. Therefore, it has been proposed that the aim of anesthetic management should be the avoidance of tachyarrhythmia and sympathetic stimulation. Sugammadex was administered as a neuromuscular reversal agent in this case. To our knowledge, this is the first case report of sugammadex use in a patient with WPW. This report presents a case of general anesthesia management in a patient with WPW syndrome. CONCLUSION: We think that it is appropriate to use sugammadex to reverse rocuronium for the prevention of sudden hemodynamic changes in patients with WPW who underwent general anesthesia.

Therapeutic Effects of Oligonol, Acupuncture, and Quantum Light Therapy in Chronic Nonbacterial Prostatitis.

This research aimed to compare anti-inflammatory effects of oligonol, acupuncture, and quantum light therapy in rat models of estrogen-induced prostatitis. Adult male Wistar albino rats were grouped as follows: Group I, control (n = 10); Group II, chronic prostatitis (n = 10); Group III, oligonol (n = 10); Group IV, acupuncture (n = 10); Group V, quantum (n = 10); Group VI, oligonol plus quantum (n = 10); Group VII, acupuncture plus oligonol (n = 10); Group VIII, quantum plus acupuncture (n = 10); and Group IX, acupuncture plus quantum plus oligonol (n = 10). Chronic prostatitis (CP) was induced by the administration of 17-beta-estradiol (E2) and dihydrotestosterone (DHT). Oligonol was given for 6 weeks at a dose of 60 mg/day. Acupuncture needles were inserted at CV 3/4 and bilaterally B 32/35 points with 1-hour manual stimulation. Quantum therapy was administered in 5-minute sessions three times weekly for 6 weeks. Lateral lobes of prostates were dissected for histopathologic evaluation. Although all of the treatment modalities tested in this study showed anti-inflammatory effects in the treatment of CP in male rats, a synergistic effect was observed for oligonol plus quantum light combination. Monotherapy with oligonol showed a superior anti-inflammatory efficacy as compared to quantum light and acupuncture monotherapies.

Analgesic effects of oligonol, acupuncture and quantum light therapy on chronic nonbacterial prostatitis.

BACKGROUND: Chronic Nonbacterial Prostatitis (CNBP) is a condition that frequently causes long-term pain and a significant decrease in the quality of life. OBJECTIVES: The present study aimed to examine the analgesic effects of oligonol, acupuncture, quantum light therapy and their combinations on estrogen-induced CNBP in rats. MATERIALS AND METHODS: This experimental study was conducted in Edirne, Turkey, using a simple randomized allocation. A total of 90 adult male Wistar rats were randomized into 9 groups of 10 rats each: Group I, control; Group II, CNBP, Group III, oligonol only, Group IV, acupuncture only; Group V, quantum only; Group VI, oligonol + quantum; Group VII, acupuncture + oligonol; Group VIII, quantum + acupuncture; Group IX, acupuncture + quantum + oligonol. Oligonol treatment was given at a dose of 60 mg/day for 6 weeks. Conceptual vessels (CV) 3 and 4, and bilaterally urinary bladder (Bl) 32 and 34 points were targeted with 1-hour acupuncture stimulation. The quantum light therapy was applied in 5-minute sessions for 6 weeks (3-times/a week). For pain measurements, mechanical pressure was applied to a point 2 cm distal to the root of the tail to elicit pain and consequent parameters (peak force, latency time of response and total length of measurement) were assessed. RESULTS: Analgesic effects were observed with all treatment regimens; however, the most prominent median analgesic effect was shown in the quantum light therapy in combination with acupuncture for estrogen-induced CNBP (PF1 = 663.9, PF2 = 403.4) (P = 0.012). Furthermore, we observed that monotherapy with quantum light showed a better analgesic efficacy as compared to oligonol and acupuncture monotherapies (PF1 = 1044.6, PF2 = 661.2) (P = 0.018, P = 0.008, P = 0.018; respectively). CONCLUSIONS: All treatment modalities showed a significant analgesic effect on CNBP in rats, being most prominent with the quantum light therapy.

Comparison of complications and procedural activities of pulmonary artery catheter removal by critical care nurses versus medical doctors.

BACKGROUND: None of the nursing studies on PA catheter removal pointed out any differences in complications after removal and procedural activities for removal of PA catheter by CCNs vs MDs in Turkey. AIMS: This quasi-experimental study was conducted to determine the occurrence and type of complications and to indicate the differences between CCNs and medical doctors' (MDs) activities for removal of PA catheter. METHODS: Totally, 60 critical care unit patients were scheduled as a sample, and they were assigned randomly to the CCN (n = 30) or to the MD (n = 30) groups. For the comparison purposes of the different activities and complications of PA catheter removal procedure between the two groups, 'Instruction Form' was followed step by step. The differences in the prevalence of variables were tested using Student's t statistics. For categorical data, Fisher's exact test was used. Significance was declared by P value of <0.05. RESULTS: Preprocedural activities like patient positioning (P < 0.001) and instructing the patient for breathing (P = 0.001) demonstrated statistically significant differences between the two groups. The PA catheters were removed properly in both groups (P > 0.05). The majority of postprocedural activities were completed successfully. The complications of the catheter removal were documented more carefully by nurses compared with doctors (P < 0.01). Additionally, singular premature ventricular complexes were observed on electrocardiogram in both groups (P > 0.05). CONCLUSION: Instructing CCNs to remove a PA catheter has been highlighted in keeping the number of complications associated with removal procedure of PA catheter.

Effects of low-dose milrinone on weaning from cardiopulmonary bypass and after in patients with mitral stenosis and pulmonary hypertension.

The phosphodiesterase inhibitor milrinone is usually preferred in patients with pulmonary hypertension and myocardial dysfunction after cardiopulmonary bypass. We investigated the effects of low-dose milrinone on pulmonary hypertension in the immediate pre- and postoperative period. Forty-seven patients were randomized to the control and milrinone groups. All patients had mean pulmonary artery pressure greater than 30 mmHg and pulmonary capillary wedge pressure greater than 20 mmHg and were candidates for mitral valve replacement for rheumatic mitral stenosis. Twenty-four patients received a loading dose of milrinone 25 microg/kg(-1) during weaning from cardiopulmonary bypass, followed by a maintenance dose of 0.25 microg/kg(-1)/min(-1) to the end of the surgery. Cardiac output and other hemodynamic variables were noted at induction, weaning from bypass, and postoperative 1 h. Pulmonary artery pressure, capillary wedge pressure, and central venous pressure were significantly lower in the milrinone group during weaning after cardiopulmonary bypass, while other variables were roughly similar. However, patients in the control group required higher doses of vasodilators, inotropes, and antiarrhythmic agents. Mean arterial pressure in the milrinone group was significantly lower at 1 h postoperatively than in the control group; however, the patients did not need many more vasopressors. Fluid restriction and diuretic agent use were more significant in the control group. Systemic arterial hypotension and vasopressor requirements with milrinone use at inotropic doses were not observed at the doses used for the study. A total of 21.7% of the patients in the control group required vasopressors in the perioperative period. Both groups demonstrated similar hematologic variables except that the hemoglobin level in the control group was significantly lower during postoperative days 1 and 7. Low-dose milrinone for a short-term during weaning from cardiopulmonary bypass may be used in patients with mitral stenosis and pulmonary hypertension for its effects on pulmonary artery pressures, less inotropic and vasopressor requirements, and fluid balance.

Nursing students' willingness to use complementary and alternative therapies for cancer patients: Istanbul survey.

It is important for student nurses to be knowledgeable of the complementary and alternative therapies and to provide accurate information to both cancer patients and other health care professionals. This study examined the nursing students' willingness to use these therapies, availability of sources of information, use of the therapies for self care, opinions about the integration of these therapies into nursing curriculum, and analyzed the differences among the responses. A self-administered questionnaire was offered to 640 nursing students in Istanbul, descriptive statistics were used, and comparisons among responses were made with chi-square test. Willingness to use for cancer patients was highest for nutritional therapy (76.1%), breathing therapies (74.5%), and massage and manipulation-Tui Na, in which pressure and touch are applied to the body (71.9%). Use of information sources was highest for nutritional therapy (75.6%), breathing therapies (71.9%), and massage and manipulation-Tui Na (62.3%). Over half of the nursing students used music therapy (54.2%), and massage and manipulation-Tui Na (53.6%) for self-care. Breathing therapies (87.2%) were the most desired therapy chosen to be included in nursing curriculum. The statistically significant differences were found among the responses related to use five therapies for care and related to desired three therapies to be included in nursing curriculum. Although students had not previously been exposed to these therapies use with oncology patients, many of students expressed a desire to integrate therapies learning into nursing curriculum. The more student nurses document high risk patients, the more effective strategies will be developed by other health care professionals.

Effects of propofol and midazolam on lipids, glucose, and plasma osmolality during and in the early postoperative period following coronary artery bypass graft surgery: a randomized trial.

It is not clear how levels of serum lipids and glucose and plasma osmolality change during propofol infusion in the pre- and postoperative period of coronary artery bypass graft surgery (CABG). This prospective, randomized, controlled trial evaluated changes in these parameters during propofol or midazolam infusion during and in the early postoperative period following surgery. Twenty patients undergoing CABG were randomized preoperatively into two groups: 10 patients received propofol (induction 1.5 mg/kg, maintenance 1.5 mg kg(-1) h(-1)) and 10 patients received midazolam (induction 0.5 mg/kg, maintenance 0.1 mg kg(-1) h(-1)). Both groups also received fentanyl (induction 20 mug/kg, maintenance 10 microg kg(-1)). Serum lipids, glucose, and plasma osmolality were measured preinduction, precardiopulmonary bypass, at the end of cardiopulmonary bypass, at the end of surgery, and 4 and 24 h postoperatively. In the propofol group, we observed a significant increase in triglycerides and very low-density lipoprotein levels 4 h postoperatively. In the midazolam group, we observed a significant decrease in low-density lipoprotein, cholesterol at the end of cardiopulmonary bypass, end of surgery, and 4 and 24 h postoperatively and significant increase in osmolality at the end of cardiovascular bypass. Changes in glucose levels did not differ significantly different between the two groups. In patients with normal serum lipids, glucose, and plasma osmolality undergoing CABG, propofol infusion for maintenance anesthesia is not associated with dangerous changes in serum lipids, glucose, and plasma osmolality compared with midazolam. A propofol infusion technique for maintenance of anesthesia for cardiac surgery where serum lipids and glucose may be of concern could be recommended as an alternative to midazolam.

Postoperative effects of opioid analgesics administered via continuous perfusion and patient controlled analgesia after open heart surgery.

Critical care nurses and physicians are familiar with the principles of patient controlled analgesia and the opioid analgesics' regimens and observations necessary for pain control in the postoperative cardiac surgical patients. The objective of the study was to compare the effects of morphine, fentanyl, meperidine, remifentanil and tramadol which were administered by patient controlled analgesia and continuous intravenous infusion combination on the various parameters. This study was designed as prospective randomised trial. Fifty patients undergone open heart surgery with sternotomy were entered equally into five randomized groups. Visual analog scale was used by researcher nurse to assess the patient' pain status. Respiratory rate, heart rate and blood gases (pO2, pCO2, SaO2), radial arterial blood pressures were measured in the first 24 hrs postoperatively. Bolus requirements were determined by physicians and side effects of the analgesics were documented. Fentanyl group showed statistically higher levels of mean pO2 (p=0.002). Meperidine had the lowest number of bolus doses (p=0.001). There were no significant differences between the groups for pain management except higher visual analog scales on tramadol. Headache, stomach-ache and, palpitations were observed in our patients. Remifentanil, meperidine, fentanyl and morphine showed similar effect with each other for pain relief except tramadol.

A modified combined approach to operative carotid and coronary artery disease: 82 cases in 8 years.

BACKGROUND: A significant number of patients undergoing coronary artery surgery have severe carotid artery disease. It is also true that up to half of the patients undergoing carotid endarterectomy (CEA) have severe treatable coronary lesions. This study aims to review data regarding 82 patients of combined approach in 8 years; the second half consists of 44 patients whose CEA was performed under local anesthesia. It compares results of the conventional and the modified approaches to simultaneous surgery. METHODS: All 82 patients who planned to have a concomitant procedure were recorded prospectively between 1995 and 2003. From 1998, the surgical technique has been modified to switch to local anesthesia for CEA, rather than perform under a single general anesthetic period. All pre-and perioperative data as well as in-hospital and outpatient control (mid- to long-term) data were recorded. A P-value of less than .05 was considered as significant. Analysis of survival was performed by using the Kaplan-Meier method and the log-rank test. RESULTS: The 30-day follow-up was 100% complete for all patients. All patients were followed for 59.59 to 114 months) months postoperatively. Three patients (6.8%) in the modified and 2 (5.2%) in the standard group had intraluminal shunting (P > .05). In the standard group, 3 patients expired and 3 had perioperative stroke; only 1 patient had a stroke in the modified group and two expired (P > .05). Mean survival time according to Kaplan-Meier test was 109.97, SE 2.84, 95% CI (104.41-115.52) months for the former group, whereas it was 62.79, SE 1.20, 95% CI (60.4565.13) months for the latter. Actuarial estimates of survival during ten-year follow up were 94.44% SE 3.83 in ten-year follow-ups and 97.67% SE 2.30 in 5-year follow-ups for the modified group (P > .05). CONCLUSIONS: Avoidance from extended periods of general anesthesia and cardiopulmonary bypass periods as well as immediate recognition of impaired cerebral flow during CEA and the time it provides to take preventive measures are the most important benefits of the modified technique without significantly changing hospital and long-term mortality and stroke. It may also reduce the cost and the waiting period for the suffering patient.
