Fulltext The display effects of patients' self-assessment on traumatic acute pain on the proportion and timing of analgesics administration in the emergency department

Rahman NH, Ananthanosamy C

Int J Emerg Med, 2014;7:36.
PMID: 25635196 DOI: 10.1186/s12245-014-0036-1

BACKGROUND: Acute pain assessment in the emergency department (ED) is important in particular during the triage process. Early pain assessment and management improve outcome. The objective of this study was to determine the effects of documentation and display of patient's self-assessment of pain using numerical rating scale (NRS) on analgesic use among adult trauma patients in ED.
METHODS: A randomized control trial was conducted recruiting 216 trauma patients who presented to ED of two tertiary centers. Pain score was done using NRS for all patients. They were randomized into pain score display group or not displayed in the control. The outcome measured were proportion of patients receiving analgesics and timing from triage to analgesic administration.
RESULTS: The proportion of patients who received analgesics when pain score was displayed was 6.5% more than when pain score was not displayed. This difference was however not statistically significant. However, stratified categorical analysis using chi-square showed that the displayed severe pain group was 1.3 times more likely to receive analgesics compared to the non-displayed group. The mean timing to analgesic administration for the displayed and non-displayed groups were 81.3 ± 41.2 (95% C.I 65.9, 96.7) and 88.7 ± 45.4 (95% C.I 69.0, 108.3), respectively (p > 0.05).
CONCLUSIONS: The proportion of patients who received analgesics increased when NRS was displayed. However, the pain display has no significant effect on the timing of analgesics.

Fulltext Ultrasonographic assessment of inferior vena cava/abdominal aorta diameter index: a new approach of assessing hypovolemic shock class 1

Rahman NH, Ahmad R, Kareem MM, Mohammed MI

Int J Emerg Med, 2016 Dec;9(1):8.
PMID: 26894896 DOI: 10.1186/s12245-016-0101-z

We designed this study to expand the usage of ultrasound to detect early occurrence of hypovolemia. We explore the potential use of inferior vena cava (IVC) and abdominal aorta (AA) diameter index (IVC:AA) measured ultrasonographically to detect class 1 hypovolemic shock with blood loss less than 15%.ᅟ
Fulltext Burden of motorcycle-related injury in Malaysia

Rahman NH, Baharuddin KA, Mohamad SM

Int J Emerg Med, 2015;8:17.

Road traffic injury (RTI) contributes to major morbidity and mortality in both developed and developing countries. Most of the injuries are caused by road-related injuries that specifically relate to motorcycle crash. We attempted to conduct a short survey to determine the magnitude of burden related to motorcycle-related RTIs in Malaysia. We hypothesize that motorcycle-related RTI in Malaysia contributes significantly to the health burden in the country.
Fulltext Intravenous parecoxib sodium as an analgesic alternative to morphine in acute trauma pain in the emergency department

Baharuddin KA, Rahman NH, Wahab SF, Halim NA, Ahmad R

Int J Emerg Med, 2014;7(1):2.
PMID: 24386899 DOI: 10.1186/1865-1380-7-2

BACKGROUND: Parecoxib sodium is the first parenteral COX-2 inhibitor used for pain management licensed for postoperative pain. However, no study has assessed the usage of parecoxib for acute traumatic pain in the emergency department (ED). The objective of this study was to investigate a potential alternative analgesic agent in the ED by determining the mean reduction of pain score between acute traumatic pain patients who were administered with intravenous (IV) parecoxib sodium versus IV morphine sulfate. The onset of perceptible analgesic effect and side effects were also evaluated.
METHODS: A randomized, double-blinded study comparing IV parecoxib 40 mg versus IV morphine at 0.10 mg/kg was conducted in adult patients presented with acute traumatic pain with numeric rating scale (NRS) of 6 or more within 6 hours of injury. Patients were randomized using a computer-generated randomization plan. Drug preparation and dispensing were performed by a pharmacist. Periodic assessment of blood pressure, pulse rate, oxygen saturation, and NRS were taken at 0, 5, 15, and 30 minute intervals after the administration of the study drug. The primary outcome was the reduction of NRS. Side effect and drug evaluation was conducted within 30 minutes of drug administration.
RESULTS: There was no statistically significant difference in the reduction of mean NRS between patients in the IV parecoxib group or IV morphine group (P = 0.095). The mean NRS for patients treated with IV morphine were 7.1 at 0 minutes, 4.5 at 5 minutes, 3.1 at 15 minutes, and 2.0 at 30 minutes. Whereas mean NRS for patients who received IV parecoxib were 7.8 at 0 minutes, 5.7 at 5 minutes, 4.7 at 15 minutes, and 3.9 at 30 minutes. The onset of perceptible analgesic effects could be seen as early as 5 minutes. Dizziness was experienced in 42.9% of patients who received IV morphine compared to none in the parecoxib group.
CONCLUSIONS: There was non-significant trend toward superiority of IV morphine over IV parecoxib. Looking at its effectiveness and the lack of opioid-related side-effects, the usage of IV parecoxib sodium may be extended further to a variety of cases in the ED.

According to the class of hypovolaemic shock, a blood loss less than 750 ml is not associated with the physiological changes. As a result it may cause a delay in fluid resuscitation. We postulate inferior vena cava (IVC) diameter reduction in inspiration and expiration may resemble the significant volume of blood loss in a healthy adult. We conducted a study to examine the changes of the IVC diameter pre and post blood donation.The inferior vena cava diameter during inspiration (IVCi) and expiration (IVCe) were measured using ultrasound (GE HEALTH) in supine position before and after blood donation of 450 ml. Paired t-test and Wilcoxin rank test were used to analyse the data. Forty two blood donors enrolled during the study period. The mean age of blood donors was 32.3 +/- 8.9 and mainly male blood donors. The mean IVCe of pre and post blood donation was 18.5 +/- 6.2 mm (95%CI 18.23, 18.74) and 16.6 +/- 6.6 mm (95%CI 16.35, 16.76) respectively. Meanwhile, the mean IVCi of pre and post blood donation was 17.1 +/- 8.6 mm (95%CI 16.89,17.30) and 15.6 +/- 6.6 mm (95%CI 15.43,15.81) respectively. The mean difference of IVCe pre and post blood donation was 1.9 +/- 0.5 mm (95%CI 1.75, 2.13) (p<0.001). In contrast, the mean difference of IVCi pre and post blood donation was 1.5 +/- 0.5 mm (95%CI 1.34, 1.68) (p<0.001). As a conclusion, the measurement of IVC diameter by ultrasound can predict the volume of blood loss in simulated type 1 hypovolaemia patient.

Fulltext Correlations between capnographic waveforms and peak flow meter measurement in emergency department management of asthma

Nik Hisamuddin NA, Rashidi A, Chew KS, Kamaruddin J, Idzwan Z, Teo AH

Int J Emerg Med, 2009 Feb 24;2(2):83-9.
PMID: 20157449 DOI: 10.1007/s12245-009-0088-9

BACKGROUND: The usual method for initial assessment of an acute asthma attack in the emergency room includes the use of peak flow measurement and clinical parameters. Both methods have their own disadvantages such as poor cooperation/effort from patients (peak flow meter) and lack of objective assessment (clinical parameters). We were looking into other methods for the initial asthma assessment, namely the use of capnography. The normal capnogram has an almost square wave pattern comprising phase 1, slope phase 2, plateau phase 3, phase 4 and angle alpha (between slopes 2 and 3). The changes in asthma include decrease in slope of phase 2, increase in slope 3 and opening of angle alpha.
AIMS: Our objective was to compare and assess the correlation between the changes in capnographic indices and peak flow measurement in non-intubated acute asthmatic patients attending the emergency room.
METHODS: We carried out a prospective study in a university hospital emergency department (ED). One hundred and twenty eight patients with acute asthma were monitored with peak flow measurements and then had a nasal cannula attached for microstream sampling of expired carbon dioxide. The capnographic waveform was recorded onto a PC card for indices analysis. The patients were treated according to departmental protocols. After treatment, when they were adjudged well for discharge, a second set of results was obtained for peak flow measurements and capnographic waveform recording. The pre-treatment and post-treatment results were then compared with paired samples t-test analysis. Simple and canonical correlations were performed to determine correlations between the assessment methods. A p value of below 0.05 was taken to be significant.
RESULTS: Peak flow measurements showed significant improvements post-treatment (p < 0.001). On the capnographic waveform, there was a significant difference in the slope of phase 3 (p < 0.001) and alpha angle (p < 0.001), but not in phase 2 slope (p = 0.35). Correlation studies done between the assessment methods and indices readings did not show strong correlations either between the measurements or the magnitude of change pre-treatment and post-treatment.
CONCLUSION: Peak flow measurements and capnographic waveform indices can indicate improvements in airway diameter in acute asthmatics in the ED. Even though the two assessment methods did not correlate statistically, capnographic waveform analysis presents several advantages in that it is effort independent and provides continuous monitoring of normal tidal respiration. They can be proposed for the monitoring of asthmatics in the ED.

Junior doctors are often the "first line" doctors called to attend to patients in cardiac arrest. We performed an anonymous questionnaire study from October 2008 to December 2008 to assess the knowledge, attitude and skill of cardiopulmonary resuscitation among junior doctors in Hospital Universiti Sains Malaysia and Hospital Raja Perempuan Zainab II. Out of the 100 questionnaire forms sent out, 70 were returned completed. The majority (85.8%) stated that they were not confident of managing a resuscitation case. There was a statistically significant (p<0.001) association between duration of clinical practice and confidence level. Up to 77.1% said that BLS should be re-certified every two years.

BACKGROUND: Good coronary care begins from the patient's home, including early transportation. As such, it is recommended that the patients activate ambulances, rather than to use their own transportations to reach the hospitals. It is not known whether Malaysian patients prefer to use private transportations or ambulances when they develop chest pain.

OBJECTIVES: This study is conducted to explore the question of the choice of transportation modes among patients with acute coronary syndrome and the reasons behind their choices.

METHODS: This is a structured interview survey on patients diagnosed with acute coronary syndrome (ACS) in emergency department of Hospital Universiti Sains Malaysia from April 2012 to September 2012.

RESULTS: Out of the 110 patients surveyed, 105 (95.5%) patients chose to use own transportation when they developed symptoms suggestive of ACS. Only 3 patients (2.7%) came to the emergency department within 1 hour of onset, and all these 3 patients chose to use ambulances as their modes of transportation. None of the patients who chose own transportation came within the first hour of symptoms onset. This is shown to be statistically significant (p<0.001). The level of education as well as past history of ischemic heart disease did not significantly influence the patients' choice of transportation.

CONCLUSION: The admonishment by various international resuscitation councils that patients with chest pain should be transported via ambulances may not be as straightforward as it seems. Numerous local and regional socio-cultural and logistic factors may need to be addressed.
