External Validation of a Recently Developed Population Pharmacokinetic Model for Hydromorphone During Postoperative Pain Therapy.

Background And Objective: We recently developed a new population pharmacokinetic model for hydromorphone in patients including age and bodyweight as covariates. The aim of the present study was to evaluate prospectively the predictive performance of this new model during postoperative pain therapy.

Methods: This was a prospective, single-blinded, randomized, single-center study with two parallel arms.

Patient-controlled Analgesia with Target-controlled Infusion of Hydromorphone in Postoperative Pain Therapy.

Background: Patient-controlled analgesia (PCA) is a common method for postoperative pain therapy, but it is characterized by large variation of plasma concentrations. PCA with target-controlled infusion (TCI-PCA) may be an alternative. In a previous analysis, the authors developed a pharmacokinetic model for hydromorphone.

Complete recovery after out-of-hospital cardiac arrest with prolonged (59 min) mechanical cardiopulmonary resuscitation, mild therapeutic hypothermia and complex percutaneous coronary intervention for ST-elevation myocardial infarction.

We report on a 68 years old survivor of an out-of-hospital cardiac arrest with favorable neurological outcome following prolonged cardiopulmonary resuscitation (CPR 59 min) until return of spontaneous circulation (ROSC) due to ST-elevation myocardial infarction (STEMI). The case demonstrates the beneficial effect of an optimal rescue chain including basic life support performed by trained bystanders, short response time of the emergency medical service, uninterrupted CPR during transportation using a mechanical chest compression system (LUCAS®), in combination with optimal intensive care management of cardiogenic shock after ROSC including multivessel emergency percutaneous coronary intervention (PCI) and intravascular therapeutic hypothermia (Coolgard®-System).
