Haloperidol-Midazolam vs. Haloperidol-Ketamine in Controlling the Agitation of Delirious Patients; a Randomized Clinical Trial.

Introduction: Agitation management in delirious patients is crucial in a crowded emergency department (ED) for both patient and personnel safety. Benzodiazepines, antipsychotics, and newly derived ketamine are among the most commonly used drugs in controlling these cases. This study aimed to compare the effectiveness of haloperidol-midazolam with haloperidol-ketamine combination in this regard. Methods: In this double-blind randomized clinical trial, delirious patients with agitation in ED were randomly assigned to a group: group A: haloperidol 2.5 mg IV and midazolam 0.05 mg/kg IV or group B: haloperidol 2.5 mg IV and ketamine 0.5 mg/kg IV. Sedative effects as well as side effects at 0, 5, 10, 15, 30 minutes and 1, 2, 4 hours after the intervention were compared between the 2 groups. Results: We enrolled 140 cases with Altered Mental Status Score (AMSS)≥+2 and mean age of 52.819.4 years (78.5% male). Agitation was significantly controlled in both groups (p<0.05). In group B, AMSS score was more significantly and rapidly reduced 5 (p = 0.021), 10 (p = 0.009), and 15 (p = 0.034) minutes after drug administration. After intervention, oxygen saturation was significantly decreased in group A 5 (p = 0.031) and 10 (p = 0.019) minutes after baseline. Time required to the maximum effect was significantly lower in group B versus group A (p=0.014). Less patients in group B had major side effects (p=0.018) and needed physical restraint (p=0.001). Conclusions: Haloperidol-ketamine can control agitation in delirium more rapidly than haloperidol-midazolam. This combination had lower adverse events with lower need for physical restraint.

Effectivness of Nebulized Budesonide for COPD Exacerbation Management in Emergency Department; a Randomized Clinical Trial.

INTRODUCTION: Nebulized budesonide has been long used in chronic obstructive pulmonary disease (COPD) exacerbation. This study aimed to compare the effectiveness of nebulized budesonide (NB) versus oral prednisolone (OP) in increasing peak expiratory flow rate (PEFR) of COPD patients in emergency department (ED). METHODS: Patients with COPD exacerbation, referring to ED were enrolled in this randomized trial study. In the first group, NB 0.5 mg every 30 minutes till three doses, placebo tablet, and standard treatment was administered. In the second group, nebulized normal saline, OP tablet 50 mg, and standard treatment were administered. Patients' demographic data, vital signs, PEFR, venous blood gas (VBG) analysis, disposition, and patient and physician satisfaction were all collected and compared between the two groups. RESULTS: 43 patients in the NB group and 41 patients in the OP group were evaluated. The two groups had similar age (p=0.544) and gender (p=0.984) distribution, duration of illness (p=0.458), and baseline PEFR (p=0.400). 12 and 24 hours after treatment, significant increase in PEFR in the NB and OP groups were observed (p=0.032 and 0.008; respectively). The upward trend of PEFR in NB group was significantly better than that of OP group during 24 hours of treatment (p=0.005). Vital signs and VBG results showed no significant differences between the two groups during the studied time interval. CONCLUSION: NB, compared to OP, could more effectively increase PEFR and ameliorate disease severity of patients with COPD exacerbation at 12 and 24 hours after treatment in ED.

Association of optic nerve sheath diameter in ocular ultrasound with prognosis in patients presenting with acute stroke symptoms.

BACKGROUND: Measurement of optic nerve sheath diameter (ONSD) by means of ocular ultrasound (US), can diagnose elevated intracranial pressure (ICP). Stroke accompanied by elevated ICP might have a worse prognosis. OBJECTIVE: To determine the relationship of ONSD in ocular US with prognosis in acute stroke in the emergency department (ED). METHODS: Patients with acute presentations of stroke, presenting to the ED in 2017 (during six months), were enrolled in our study. US exam was performed on all of them and ONSD was determined in two longitudinal and transverse dimensions. Demographic data, rate of patients' admission in the ward or intensive care unit, one-month patients' outcome and type of stroke were recorded. The relationship of mean ONSD was evaluated with study variables. RESULTS: In this study, 60 patients were enrolled. The mean ±â€¯SD ONSD in the deceased cases was 4.40 ±â€¯0.64 mm and in the survived patients was 3.83 ±â€¯0.56 mm. Youden index calculated ONSD>3.9 mm as the best cut-off point in mortality prognosis. It has a sensitivity of 83.3% and a specificity of 59.2%. CONCLUSIONS: Increased ONSD had a direct relationship with mortality rate in acute stroke.
