Anesthesia advanced circulatory life support

The constellation of advanced cardiac life support (ACLS) events, such as gas embolism, local anesthetic overdose, and spinal bradycardia, in the perioperative setting differs from events in the pre-hospital arena. As a result, modification of traditional ACLS protocols allows for more specific etiology-based resuscitation. Perioperative arrests are both uncommon and heterogeneous and have not been described or studied to the same extent as cardiac arrest in the community. These crises are usually witnessed, frequently anticipated, and involve a rescuer physician with knowledge of the patient's comorbidities and coexisting anesthetic or surgically related pathophysiology. When the health care provider identifies the probable cause of arrest, the practitioner has the ability to initiate medical management rapidly. Recommendations for management must be predicated on expert opinion and physiological understanding rather than on the standards currently being used in the generation of ACLS protocols in the community. Adapting ACLS algorithms and considering the differential diagnoses of these perioperative events may prevent cardiac arrest

Impact of ambient air pollution on human health health in the Nelson Mandela Bay Municipality

The aim of this study was to assess whether ambient-air pollution contributed negatively to ambient-air quality, and subsequently to human health in the Nelson Mandela Bay Municipality (the study area). A research design that is descriptive and explorative in nature was followed. The research methodology conformed to the following procedure. Firstly, an emission inventory of one hundred and fifty (150) emission sources listed on the data base of the Nelson Mandela Bay Municipality was compiled (“N” and “n” = 150) in a quantitative research approach. Emission data from these sources, together with the relevant meteorological data from the weather stations in the study area (“N” and “n” = 5) were collected and used as input into a geographical information system-software program to quantify the contribution of each emission source to ambient air pollution. The said software program was also used to simulate the dispersion of emissions over the study area. The emission inventory was compiled in consultation with a focus group of experts in the field of air-pollution control in a qualitative-research approach. Secondly, health records of the patients who attend the clinics in the said municipality (“N” and “n” = 49) were assessed for air pollution-related health outcomes. Nineteen (19) of the forty-nine (49) clinics were situated in Sub-District A; fifteen (15) clinics were situated in Sub-District B. The last fifteen of the clinics were situated in Sub-District C, which was also the least-industrialised sub-district. Sub-districts A and B were found to be the most industrialised of the three Sub-districts. Air pollution related health statistics were compiled for the following air-pollution-related health outcomes, namely: lower respiratory tract infections in children under five (5) years of age, as well as pneumonia and asthma in the general population

The experience of childbrith in first-time mothers who received narcotic analgesics during the first stage of labour

This research has focused on the birthing experience of first-time mothers who received the narcotic analgesic combination of Pethidine and Hydroxyzine during the first stage of labour. A qualitative research methodology was used to collect data. Unstructured interviews were held with first-time mothers to obtain accounts of their experience of childbirth. These narrations were audio-taped while the participants were still being cared for in the postnatal ward of the hospital where delivery took place. Nine interviews were conducted with first-time mothers who gave birth normally vaginally after a normal pregnancy and who received a narcotic analgesic in the first stage of labour. The transcribed interviews were analyzed using Tesch’s method of descriptive analysis (in Creswell, 1994:115)

In-service education and training as experienced by registered nurses

Nursing is a dynamic profession that is subject to rapid changes in health care provision, hence the need for inservice training programmes for nurses. Newly employed registered nurses require in-service training in order to update them regarding the latest developments in nursing practice. The researcher noted that some newly appointed registered nurses were not competent in all aspects relating to their tasks. This could have been due to a knowledge deficit relating to either new developments or of the procedure relating to a specific task. In some institutions newly-appointed registered nurses on probation reported not receiving in-service training for six months or longer, yet they were still expected to perform their tasks efficiently. The objectives of the study were to, firstly, explore and describe the experiences of registered nurses regarding in-service training programmes in their institutions and, secondly, to make recommendations to Nursing Service Managers relating to the development of effective inservice training programmes in their institutions. A qualitative, exploratory, descriptive design was implemented. Data was analysed using Tesch’s descriptive approach
