RESUMO
Background: In order to achieve the major goals of transformation in the health care system, organizing and developing the existing potential properly play a pivotal role. The objective is to conduct a scoping review to describe available extent of literatures about scattered structure, process, and outcome factors of the clinical specialist nurse and redesign those as three cohesive and interconnected factors. Materials and Methods: A scoping review of studies was conducted from 1970 to June 20, 2020, focusing on the structure, process, and outcome factors of the clinical specialist nurse from six databases. Results: Forty-six studies were carried out. Structure (individual characteristics, intra-organizational, and governance factors), process (professional interactions, and roles and duties of a specialist nurse), and outcome (patient and family, nurse, and organizational outcomes) factors were identified. Conclusions: With the correct knowledge of the factors, it is possible to achieve the desired therapeutic, organizational, and professional results of nursing by providing the necessary fields in the structure, process, and outcomes. The identification of structures, processes, and outcomes that influence clinical nurse's role implementation may inform strategies used by providers and decision makers to optimize these roles across healthcare settings and guarantee the delivery of high-quality care.
RESUMO
BACKGROUND: Surgery for hip fractures can be done under general or neuraxial anesthesia. This study aimed to compare these two methods concerning their postoperative complications, duration of operation, hospitalization and the mortality rate within a period of one month after surgery. METHODS: 400 patients aged more than 30 years old and scheduled for elective operative fixation of fractured hip, randomly enrolled in two equal groups of general (GA) and neuraxial (NA) anesthesia. Hemoglobin level was measured before and 6 hours, 2, 3 and 5 days after the surgery. The intra and postoperative blood loss, duration of surgery, the severity of pain at the time of discharge from recovery and at the 2(nd), 3(rd) and 5(th) postoperative days were recorded. Statistical analysis was performed using SPSS version 12.0 by Mann-Whitney, chi-square, and t tests. P < 0.05 was considered significant. RESULTS: Both groups were similar regarding age, weight, and gender ratio. There was no significant difference in baseline hemoglobin, duration of surgery, length of hospitalization before surgery and the type of surgery. The mean of intraoperative blood loss and visual analogue score (VAS) in recovery and at the 3(rd) postoperative day, and also the length of hospitalization after surgery were significantly less in neuraxial anesthesia group. Both groups showed a significant decrease in hemoglobin values on the 2(nd) and 3(rd) postoperative days comparing to the baseline (p < 0.001). CONCLUSIONS: The morbidity and mortality rates of patients undergoing hip surgery were similar in both methods of anesthesia, but postoperative pain, blood loss, and duration of hospitalization were more in patients undergoing general anesthesia.
RESUMO
BACKGROUND: Ketamine is a potent analgesic agent in addition to its anesthetic properties. Oral ketamine has been used to treat postoperative stump pain following lower limb amputation. In this study, oral ketamine was used to reduce the severity of postoperative pain following orthopedic surgery. METHODS: Seventy-two adult traumatic patients undergoing orthopedic operations were randomly divided into ketamine and placebo groups. In ketamine group, oral ketamine administered at 8-hour intervals postoperatively. Severity of postoperative pain, amount of morphine used, and the time to first rescue analgesic were determined and compared between two groups. RESULTS: Patients in ketamine group had significantly lower scores of postoperative pain (5.2 +/- 1.2, 4.9 +/- 1.6, 4.4 +/- 2.2, 4.3 +/- 1.5, and 3.4 +/- 1.3 at 2, 4, 8, 16, and 24 h postoperatively vs. 7.7 +/- 1.5, 7.3 +/- 1.6, 6.3 +/- 1.9, 6.0 +/- 1.6, and 5.1 +/- 1.8 in placebo group; P < 0.05). The amount of morphine required in the first postoperative day was significantly lower in ketamine group (10.1 +/- 5.6 mg vs. 13.4 +/- 7.8 mg in placebo group; P < 0.05). Time to first rescue analgesic in the ward was significantly longer in ketamine group (3.5 +/- 1.5 h vs. 1.9 +/- 1.2 h in placebo group; P < 0.05). A female patient in ketamine group developed postoperative emergence reaction following extubation. CONCLUSIONS: Oral ketamine may be used to reduce postoperative pain following orthopedic procedures in the traumatic patients. Since only one patient developed psychological side effect (which we can not attribute to ketamine with certainty) it can be concluded that oral ketamine is not so fearsome with respect to emergence reaction.
