Postoperative nausea and vomiting in korle bu teaching hospital
G Amponsah
Ghana Medical Journal , 2007,
Abstract: Objective: Postoperative nausea and vomiting (PONV) is one of the most distressing morbidities associated with surgery. Even though the incidence can be as high as 30% elsewhere no work has been done to assess the incidence in any health facility in Ghana. This study was carried out to find out the incidence, risk factors and the management of PONV in a tertiary healthcare facility. Design: This was a prospective study. Setting: The study was carried out in Korle Bu Teaching Hospital (KBTH). Subjects and Methods: All patients above the age of 18 years who had surgery including general surgery were included in the study. Information obtained using a questionnaire included demographic data, the type of anaesthesia, the incidence of PONV and its management. Results: Three hundred and six (306) completed forms out of 322 questionnaires were analyzed. One hundred and six patients (34%) had episodes of PONV of whom 82 (77.4%) had intra-operative opioids. Of the other factors only age was found to be a risk factor with patients in the 20-49 age group constituting 71.8% (p= 0.007). Eleven out of 93 patients who reported the episode to a health worker received medication for their PONV. Drugs used included promethazine and antimalaria. Conclusions: Thirty-four percent of patients in the study had PONV indicating that the problem is not uncommon among post-surgical patients in KBTH. Awareness of the problem should be highlighted and adequate management should be given to all patients. Patients at risk should be identified and appropriate management instituted.
Laparoscopic cholecystectomy at the Korle Bu Teaching Hospital, Accra, Ghana: An initial report
JNA Clegg-Lamptey, G Amponsah
West African Journal of Medicine , 2010,
Abstract: BACKGROUND: Laparoscopic cholecystectomy (LC) the preferred treatment for gallstones was not available in Ghana until 2005. OBJECTIVE: To report experience from Ghana of laparoscopic cholecystectomy in the treatment of galestones. METHODS: In a prospective study of patients with gallstones, information was obtained on demography, duration of various stages of the operation, analgesia and complication of patients with gallstones. All patients had general anaesthesia using endotracheal intubation, muscle relaxant and intermittent positive pressure ventilation. A standard four-trocar technique and maximum pneumoperitoneum pressure of 14mmHg were maintained during surgery. RESULTS: There were 50 women and two men aged 17-72 years (mean 44.2 years). All had symptomatic gallstones treated by interval LC. The main indications were biliary colic 23(44%) and previous cholecystitis 15(29%). There were scars from previous abdominal surgery in 22 (42%), mainly pfannenstiel. The Verres needle was used to obtain pneumoperitoneum in 40 (77%). Only one patient (1.9%) had the operation converted to open cholecystectomy. Most patients, 47/51 (92%), were discharged in 24 hours. The mean durations of various stages were: anaesthesia (110 minutes), pneumo-peritoneum (67.5 minutes) and reverse trendelenburg (47.8 minutes). The mean operating time reduced from 81 to 68 minutes in the last 20 patients. Complications were sore throat 11(21.6%), infection of the umbilical wound 3(5.9%), right shoulder tip pain (3; 5.9%) and bile leak 1(2%). There was no peri-operative mortality. CONCLUSION: Elective laparoscopic cholecystectomy can be performed with good results in patients with symptomatic gallstones in Accra.

Challenges of anaesthesia in the management of the surgical neonates in Africa
Amponsah Gladys
African Journal of Paediatric Surgery , 2010,
Abstract: Africa has one of the highest neonatal mortalities in the world, for which the commonest causes do not include surgical conditions such as some congenital anomalies that are amenable to surgery but are not often operated on because of a number of challenges. These challenges include cultural beliefs and practices, dearth of human resource capacity, inadequate laboratory and imaging support and lack of consumables and intensive or high dependency care facilities. Some of these challenges will be examined and highlighted using the acronym "ASKS" in this article.
Evaluation of Food Hygiene Knowledge Attitudes and Practices of Food Handlers in Food Businesses in Accra, Ghana  [PDF]
George Amponsah Annor, Ekua Anamoaba Baiden
Food and Nutrition Sciences (FNS) , 2011, DOI: 10.4236/fns.2011.28114
Abstract: Food handlers have a prime role to play in food businesses, and that is to guarantee that meals served are hygienic for consumption. Conscious or inadvertent contamination of such food places consumers at risk of suffering from food- borne illnesses. For this reason the study was carried out to document the food hygiene knowledge, attitudes and practices of some food handlers, in food businesses in Accra, Ghana and also to determine the microbiological load of the foods sold by the food businesses. The study targeted food handlers in the hotel industry. The study involved a field survey, followed by a laboratory assessment of microbiological status of food samples obtained from the sampled hotels. Cross tabulations and chi – squared tests (5% significance level) as well as frequency distributions were used to analyze the data obtained from the field survey. Data obtained from the laboratory assessment were also compared to standard values of microbiological counts. Majority of respondents were between the ages of 30 - 40 years (42.9%) with tertiary or post secondary education. Food hygiene knowledge and attitudes were satisfactory, however its practice was challenging. Gender, age and educational level of respondents did not influence their food hygiene practices. Microbial counts of all food samples was generally high ranging from 1.2 × 105 CFU/g to 1.1 × 108 CFU /g. The total coliform counts of foods ranged from 1.0 × 104 CFU/g to 5.0 × 106 CFU/g, and these were obtained from three out of the five hotel kitchens sampled. The study concluded that, the food hygiene knowledge and attitudes of the food handlers did not result in efficient food hygiene practices.
Function optimization over integral domain: Comparative performance of elite genetic algorithm for small iterariions and small generation size
SK Amponsah, KF Darkwah
Journal of Science and Technology (Ghana) , 2007,
Abstract: In this paper we present a version of the Genetic Algorithm (GA), which we call XSGA to find integral suboptimal global solution of one variable multimodal functions. XSGA makes use of local search and restarts. Our proposed XSGA works better than the elite Genetic Algorithm for small generation size and small number of iterations. Both versions of the GA work well for larger generation size and larger number of iterations. Journal of Science and Technology(Ghana) Vol. 27 (1) 2007: pp. 61-74
Seismic activity in Ghana: past, present and future
P. E. Amponsah
Annals of Geophysics , 2004, DOI: 10.4401/ag-3319
Abstract: Though Ghana is far away from the major earthquake zones of the world, it is prone to earthquake disaster. Ghana has records of damaging earthquakes dating as far back as 1615. The last three major events occurred in 1862, 1906 and 1939. This paper presents the main historical and current instrumental recorded earthquakes of Ghana and the steps being taken to mitigate the negative effects of such disastrous occurrences in the country. The discussion is based on historical and current data obtained from the seismological observatories in Accra and Kukurantumi. Historical earthquakes of magnitude greater than 6.0 and current local tremors with magnitudes ranging from 1.0 to 4.8 on the Richter scale have been recorded since the establishment of the seismograph stations.
Occupational Health and Safety and Sustainable Development in Ghana
Kwesi Amponsah-Tawiah
International Journal of Business Administration , 2013, DOI: 10.5430/ijba.v4n2p74
Abstract: This paper examines the state of occupational health and safety in Ghana and the role it plays in the sustainable development agenda of the country. It reviews literature on the triple bottom line (people, profits and planets) and how they are affected by OHS policies and the effects of work related hazards on sustainable development. The paper observes the argument that there are three pillars of sustainable development; people, planet and profit. The paper also reveals that OHS has three pillars similar to sustainability; Economy, Environment and Society. It thus recommends that there should be sound OHS policies that will embrace sufficient environmental friendly programmes to ensure that the employees are safe and hence ensure sustainability.
Mothers’ Demand for Preventive Health Care for Children aged Under-Five Years: The Case of Utilization of Insecticide-Treated Bednets in Ghana.

Journal of Sustainable Development , 2010, DOI: 10.5539/jsd.v3n2p98
Abstract: Child health outcomes remain one of the most important barometers for measuring the overall social and economic well being of a country. Malaria is endemic in sub-Saharan Africa, being the major cause of under-five mortality in Ghana. An effective strategy to combat the widespread malaria morbidity among children aged under-five is the utilization of preventive health care via Insecticide Treated Bednets (ITNs). This paper examines the socio-economic factors influencing the adoption and usage of ITNs by mothers or care-givers for children aged under-five years. Logistic regression is employed for the empirical estimation. The study finds that low-income households, age of the child, area of residence, distance to the nearest health facility and distance to food market inter alia significantly predict mother’s adoption and utilization of ITN among children aged-under five. It is also worth-noting that women who had experienced childhood mortality in the last five years preceding the survey were 37 percentage points more likely to have their children sleep under ITN. In addition, mothers who profess the Catholic faith were 2.4 times more likely to have their children sleep under ITN compared to their counterparts who are traditionalist. The paper contributes to the general debate on preventive health care.
Causes and Effects of Frequent and Unannounced Electricity Blackouts on the Operations of Micro and Small Scale Industries in Kumasi
Imoro Braimah,Owusu Amponsah
Journal of Sustainable Development , 2012, DOI: 10.5539/jsd.v5n2p17
Abstract: The aim of this paper was to examine the causes and effects of the frequent and unannounced electricity blackouts on the operations of micro and small scale industries (MSI) in Kumasi, Ghana. Data from a sample of 320 MSI selected from three industrial clusters in the Kumasi metropolis, revealed that the frequent and unannounced blackouts have caused a deficit of about 5.3% in the quantity of electricity they required for continuous operations. The blackout hours were estimated to last for an average of 10.3 hours per month. As a consequence of the blackouts, about 44% of the MSI spent this duration in redundancy because of lack of alternative sources of electricity but maintained the same labour cost. The remaining 56% of the MSI obtained power from alternative sources which required an average of GH¢15.5 per month to run. The paper concludes that uninterrupted electricity supply is vital for the effectiveness of the MSI.
