“…Postoperatively, the reported effect of epidural analgesia on hypotension varied: frequency was either less (0% versus 33%, P=0.001, evidence level I), greater (40% versus 13%, P=0.01, evidence level II), or not different (evidence level II) as compared with patients receiving systemic analgesia [17,72,73]. Even though the evidence presented in the literature with regard to hypotensive events appears to be overwhelming, it must be remembered that the definition of hypotension is immensely diversified and ranges from a 20% decrease from baseline [28,32,49,65] to a systolic blood pressure of less than 90 mmHg [41]. Therefore, the conclusions of these results have to be weighed carefully.…”

“…Three citations were considered to provide Level I evidence. Many studies included a small number of patients and only few outcome parameters: there were 12 RCTs with a sample size of ≤40 patients [21,[25][26][27][28][29][30][31][32][33][34][35]. The study by McKenzie et al [36] involves one study population, whereas the other two studies by McKenzie et al [33,37] identified only subgroups of these patients.…”
