“Patients in the LB group had a reduced incidence of major complications within 90 days [19 (14.2%) patients vs. 167 (24.6%) patients] compared with patients in the control group, with an adjusted hazard ratio (HR) of 0.55 [95% confidence interval (CI) 0.34-0.89, P = .014].”

What did lifespan studies of Bupivacaine find?

DrugAge

DrugAge records 4 results from 1 paper: 2 in C. elegans and 2 in D. melanogaster. Average lifespan is the mean or the median, as each paper reports it.

What did studies of Bupivacaine find?

3

Studies of Bupivacaine measured 3 outcomes; the most studied are delirium (1 study), weight bearing (1) and mortality (1).

Delirium

no changein humans1

1 study
  1. Bupivacaine has no effect on delirium in humans (4.5% vs 7.2%, P = 0.254).

    “The incidence of delirium was similar between the two group [LB group 6 patients (4.5%) vs. control group 49 (7.2%) patients, P = 0.254].”

Weight bearing

upin humans1OR 2.4

1 study
  1. Bupivacaine improves weight bearing in humans (OR 2.40 (1.64-3.51), 54.5% vs 33.1%).

    “Seventy-three patients in the LB group (54.5%) achieved weight-bearing within 24, while 225 patients in the control group (33.1%) achieved this goal, with an odds ratio of 2.40 (1.64-3.51, P < 0.001).”

Mortality

1 study
  1. Bupivacaine has no effect on mortality in humans (HR 0.74 (0.35-1.56), 6.0% vs 8.5%).

    “death occurred in 8 (6.0%) patients of the LB group and 58 (8.5%) of the control group, with an HR of 0.74 (0.35-1.56, P = 0.432).”

What is Bupivacaine linked with?

1

Studies link Bupivacaine with 1 measure, most often major complications (1 study).

Major complications

downin humans1HR 0.55

1 study
  1. Bupivacaine lowers the risk of major complications in humans (adjusted HR 0.55 (95% CI 0.34-0.89), 14.2% vs 24.6%).

    “Patients in the LB group had a reduced incidence of major complications within 90 days [19 (14.2%) patients vs. 167 (24.6%) patients] compared with patients in the control group, with an adjusted hazard ratio (HR) of 0.55 [95% confidence interval (CI) 0.34-0.89, P = .014].”
