Several studies reported Pv-aCO2/Ca-vO2 ratio as a surrogate of VCO2/VO2 to detect global tissue hypoxia. The present study aimed to evaluate the prognostic value of Pv-aCO2/Ca-vO2 ratio combined with lactate levels during the early phases of resuscitation in septic shock. ⋯ Combination of Pv-aCO2/Ca-vO2 ratio and lactate at early stages of resuscitation of septic shock can better predict the prognosis of patients. The Pv-aCO2/Ca-vO2 ratio may become a useful parameter supplementary to lactate in the resuscitation of septic shock.

Case Reports
Potential drug interaction with opioid agonist in the setting of chronic low-dose opioid antagonist use.
Low dose naltrexone (LDN) has been evaluated in several small studies for the treatment of inflammatory conditions. It is thought to work through modulation of inflammatory mediators and upregulation of endogenous opioid receptors. This may hypersensitize patients to exogenous opioids. ⋯ The patient received a single dose of oxycodone 5mg that resulted in obtundation unresponsive to painful stimuli necessitating the administration of naloxone boluses and infusion along with admission to the intensive care unit for 1 night. The patient responded well to naloxone therapy. He was discharged in satisfactory condition.

Randomized Controlled Trial Comparative Study
A prospective randomized, double-dummy trial comparing intravenous push dose of low dose ketamine to short infusion of low dose ketamine for treatment of moderate to severe pain in the emergency department.
Compare adverse effects and analgesic efficacy of low-dose ketamine for acute pain in the ED administered either by single intravenous push (IVP) or short infusion (SI). ⋯ Low-dose ketamine given as a short infusion is associated with significantly lower rates of feeling of unreality and sedation with no difference in analgesic efficacy in comparison to intravenous push.
