The effectiveness of sodium citrate and sodium citrate/ranitidine were compared in two randomised groups of elective caesarean patients during the various phases of anaesthesia. The mean pH values (3.5, 3.3, 3.6) were lower in the citrate group compared to the citrate/ranitidine group (6.1, 6.3, 5.9). The percentage of patients with pH values less than 2.5 was 40% in the citrate group compared to 7% in the citrate/ranitidine group. Sodium citrate alone is less effective than sodium citrate/ranitidine for acid aspiration prophylaxis.

Med J Malaysia, 1991 Dec;46(4):349-55.

PMID: 1840444

The effectiveness of sodium citrate as a prophylaxis against acid aspiration syndrome was studied in 3 groups of obstetric patients. Group I was the control group which consisted of 20 patients in established labour who were not likely to require caesarean section. No antacid had been given to these patients. Group II consisted of 20 patients who underwent elective caesarean section, while Group III consisted of another 20 patients who underwent emergency caesarean section. Group II and III were given 30ml of 0.3M sodium citrate as soon as they arrived in the operation theatre. The gastric content was aspirated after the induction of anaesthesia and at the end of surgery just before extubation. The volume was measured and a sample sent for pH analysis. Sodium citrate was found to increase the gastric pH significantly in both Group II and III patients when compared with Group I patients who underwent emergency caesarean section. We conclude that 30ml of 0.3M sodium citrate is effective in increasing gastric pH though it tends to be associated with an increase in gastric volume.

Fulltext Ranitidine and sodium citrate as prophylaxis against acid aspiration syndrome in obstetric patients undergoing caesarean section

Lim SK, Elegbe EO

Singapore Med J, 1992 Dec;33(6):608-10.

PMID: 1488672

The efficacy of a single oral dose of 0.3M of sodium citrate alone as a prophylaxis against acid aspiration syndrome in obstetric patients undergoing LSCS (elective and emergency) was compared with that of intravenous ranitidine. One group of patients was given 30 ml of 0.3M sodium citrate orally just before the induction of anaesthesia while the other group was given 50mg of ranitidine intravenously together with the 30ml of 0.3M sodium citrate. This was done for both the elective and the emergency groups of patients. There was no significant difference in the mean pH of the gastric aspirate obtained from those given sodium citrate alone and those given sodium citrate and ranitidine in either the elective or the emergency group. However, in the emergency group, those who were given sodium citrate alone tend to have a larger volume of gastric aspiration when compared with those given ranitidine together with the sodium citrate. There were significantly more patients with gastric aspirates of more than 25ml in the emergency group to which sodium citrate alone was given. It would appear that supplementing an intravenous dose of ranitidine with the oral dose of sodium citrate is useful in emergency LSCS as a prophylaxis against acid aspiration syndrome.

Fulltext Neuroleptic malignant syndrome with renal and respiratory complications--a case report

Liam CK, Ong SB

Singapore Med J, 1990 Apr;31(2):182-4.

PMID: 1973548

The neuroleptic malignant syndrome is an idiosyncratic reaction to neuroleptic therapy which sometimes can be fatal because of the various associated complications. We describe a schizophrenic patient who, after commencement of haloperidol, developed this reaction which was complicated by acute oliguric renal failure and aspiration pneumonia. It is mandatory that the patient is treated in a medical intensive care unit once the syndrome is recognised. The management of the neuroleptic malignant syndrome and its complications is discussed.

PMID: 27211885 DOI: 10.11622/smedj.2016091

INTRODUCTION: Inadequate oral care has been implicated in the development of aspiration pneumonia in frail geriatric patients and is a major cause of mortality, due to the colonisation of microbes in vulnerable patients. This type of pneumonia has been associated with an increase in respiratory pathogens in the oral cavity. The aim of this study was to evaluate the effects of chlorhexidine compared to routine oral care in edentulous geriatric inpatients.

METHODS: A double-blind, parallel-group randomised controlled trial was carried out. The intervention group received oral care with chlorhexidine 0.2%, while the control group received routine oral care with thymol. Nurses provided oral care with assigned solutions of 20 mL once daily over seven days. Oral cavity assessment using the Brief Oral Health Status Examination form was performed before each oral care procedure. Data on medication received and the subsequent development of aspiration pneumonia was recorded. An oral swab was performed on Day 7 to obtain specimens to test for colonisation.

RESULTS: The final sample consisted of 35 (control) and 43 (intervention) patients. Chlorhexidine was effective in reducing oral colonisation compared to routine oral care with thymol (p < 0.001). The risk of oral bacterial colonisation was nearly three times higher in the thymol group compared to the chlorhexidine group.

CONCLUSION: The use of chlorhexidine 0.2% significantly reduced oral colonisation and is recommended as an easier and more cost-effective alternative for oral hygiene.

During a stroke, the mouth tends to become an unhealthy place and may give rise to various life-threatening conditions. To this end, there have been repeated calls to incorporate oral hygiene guidelines and practices for hospitalized stroke patients to prevent aspiration pneumonia and improve patients' oral health. The objective of the study was to determine health care providers' practices of oral health care among patients hospitalized after an occurrence of stroke and to determine health care providers' background and work environment effect on these practices. A cross-sectional study was conducted among stroke care providers in 13 public hospitals in Malaysia. The questionnaires distributed were self-administered, where nursing staff provided details of their oral health care practices for stroke patients. Information on the background of health care providers and work environment was also collected. Overall, a total of 780 responses from the registered nurses were obtained. Almost half of the respondents (48.1%) reported that they recommended toothbrushing twice or more per day to stroke patients. Two-thirds (64.7%) reported that they performed daily mouthwashing on their patient, while less than half (38.8%) reported daily oral hygiene assistance. Result of the analysis revealed that oral hygiene practices were significantly associated with having working wards ( P < 0.05), level of qualification ( P < 0.05), having oral health care guidelines ( P < 0.001), specific resources ( P < 0.05), and attending previous training in oral care ( P < 0.001). Provision of oral hygiene practices for hospitalized stroke patients is important. A lack of oral health care guidelines, support from dental professionals, specific resources, training, and assistance in daily oral care for patients is evident and detrimental to oral hygiene practices. The current findings have significant implications for new initiatives to support health care providers, particularly the registered nurses performing oral health care for hospitalized stroke patients. Knowledge Transfer Statement: This study may provide a basis of information for improving the delivery of oral health care to stroke patients. Enhancement in the training and improvement in the existing guidelines and resources is pivotal for the provision of better oral health care for the potential benefits to these patients, including their improved quality of life and disease prevention.

Fulltext Single dose antacid therapy before caesarian section

Tan KH

Med J Malaysia, 1984 Sep;39(3):246-9.

PMID: 6100563

The severity of pulmonary aspiration depends mainly on the acidity of the aspirate. Mist magnesium trisilicate (MMT) has been used for many years at the maternity unit in General Hospital, Kuala Lumpur, to neutralise the acidic gastric contents in all obstetric patients requiring caesarian section. This preliminary study shows that a single dose of 15 mls of MMT before general anaesthesia raises the intragastric pH to above the critical level of 2.5 in 80% of the patients. Recently there have been doubts over the protective role of MMT. Sodium citrate which is the other antacid available may be a better alternative.
