Fulltext Single dose antacid therapy before caesarian section

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

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.

Objectives: The objectives of the study were to assess: i) the staining susceptibility of composite resins, ii) the ability of whitening toothpastes in removing stains from composite resins.
Materials and Methods: Thirty specimens from each composite resins: Filtek Z350 (3M ESPE), Filtek Z250 (3M ESPE) and Beautifil (Shofu Inc.) were fabricated. After polishing, specimens were immersed in coffee for 3 days. Specimens were then brushed twice a day for 2 weeks using Colgate Total (Colgate-Palmolive, control group), Colgate Advanced Whitening (Colgate- Palmolive, test group) and Darlie All Shiny White (Hawley & Hazel Chemical Co., test group). Colour changes (?E*) were measured using Spectrophotometer at baseline, after coffee immersion and after brushing. Results were statistically analyzed using one way ANOVA and Tukey’s test.
Results: There was significant difference in terms of colour changes for Filtek Z350, Filtek Z250 and Beautifil after coffee immersion (P0.05).
Conclusions: Filtek Z350 was able to resist staining by coffee better than Filtek Z250 and Beautifil. The whitening toothpastes did not offer added advantage in terms of ability to remove stains compared to ordinary toothpaste.

This paper reports an alternative method for making glass-ceramic from disposal waste water
sludge and soda lime silica (SLS) glass. The glass ceramic samples were prepared from a mixture
of wastewater sludge and SLS glasses, melted at 1375°C for 3 hours and quenched by pouring into
water to obtain a coarse frit. The frit glass was then crushed and sieved to 106μm before it was
pressed to a pellet. The sintering process was performed at various temperatures between 700-
1000°C for 2 hours and morphologically characterized with XRD, SEM, and EDX. Overall results
showed the crystalline phase of diopside sodian-critobalite glass-ceramic is depending on thermal
treatment process and making them attractive to industrial uses such as in construction, tiling, and
glass-ceramic applications.

BACKGROUND: Late-night supper increases the risk of postprandial reflux from the acid pocket especially in obesity. An alginate-based, raft-forming medication may be useful for obese patients with GERD.

AIMS: To compare the efficacy of Gaviscon Advance (Reckitt Benckiser, UK) and a non-alginate antacid in post-supper suppression of the acid pocket and post-prandial reflux among obese participants.

METHODS: Participants underwent 48 h wireless and probe-based pH-metry recording of the acid pocket and lower oesophagus, respectively, and were randomised to single post-supper (10 pm) dose of either Gaviscon Advance or a non-alginate antacid on the second night. Primary outcomes were suppression of median pH of acid pocket and lower oesophagus, measured every 10-minutes post-supper for 1 h. Secondary outcomes were suppression of % time pH acid pocket but not the lower oesophagus was suppressed with Gaviscon Advance vs antacid (all P acid pocket. (Clinical trial registration unique identifier: NCT03516188).
