Vasopressin and methylprednisolone improve outcomes during in hospital cardiac arrest: JAMA

The results of the study are as follows:

· Among 512 patients who were randomized, 501 met all inclusion and no exclusion criteria and were included in the.

· One hundred of 237 patients (42%) in the vasopressin and methylprednisolone group and 86 of 264 patients (33%) in the placebo group achieved return of spontaneous circulation.

· At 30 days, 23 patients (9.7%) in the intervention group and 31 patients (12%) in the placebo group were alive.

· A favourable neurologic outcome was observed in 18 patients (7.6%) in the intervention group and 20 patients (7.6%) in the placebo group at 30 days (risk ratio, 1.00; risk difference, 0.0%.

· In patients with return of spontaneous circulation, hyperglycemia occurred in 77 (77%) in the intervention group and 63 (73%) in the placebo group.

· Hypernatremia occurred in 28 (28%) and 27 (31%), in the intervention and placebo groups, respectively.

Thus, the researchers concluded that among patients with in-hospital cardiac arrest, administration of vasopressin and methylprednisolone, compared with placebo, significantly increased the likelihood of return of spontaneous circulation. However, there is uncertainty whether this treatment results in benefit or harm for long-term survival.
