Implementation of a nurse-driven pASP reduced the total dose of benzodiazepines and the occurrence of withdrawal symptoms significantly.

We demonstrated recently that the implementation of a nurse-driven analgesia and sedation protocol (pediatric analgesia and sedation protocol [pASP]) for mechanically ventilated nonpostsurgical patients reduces the total dose of benzodiazepines and the withdrawal symptoms significantly. It has not been investigated if these results can also be expected in the group of patients undergoing surgery. To evaluate the effects of the pASP in mechanically ventilated postsurgical children regarding drug dosage, duration of mechanical ventilation, length of stay, and rate of withdrawal symptoms. This is a two-phase prospective observational control study. The preimplementation group was managed by the physician's order and the postimplementation group was managed with the pASP including COMFORT-B, nurse interpretation of sedation, and Sophia observation withdrawal symptoms scale scoring. One hundred and sixteen patients were included before and one hundred and ten patients after implementation. The pASP had no effect on length of pediatric intensive care unit stay or duration of mechanical ventilation. The protocol reduced total (5.0 mg/kg [0.5-58.0] vs 4.0 mg/kg [0.0-47.0]; = 0.021) and daily doses (4.4 mg/kg/d [1.1-33.9] vs 2.9 mg/kg/d [0.0-9.9]; < 0.001) of benzodiazepines significantly. No difference was observed in total and daily doses of opioids (5.0 mg/kg [0.1-67.0] vs 3.0 mg/kg [0.1-71.0]; = 0.81) and (0.7 mg/kg/d [0.0-7.0] vs. 0.8 mg/kg/d [0.0-3.7]; = 0.35), respectively. Rate of withdrawal symptoms was significantly lower after implementation (35.3 vs 20.0%; = 0.01), but not in patients after solid organ transplantation or oncological patients. The nurse-driven analgesia and sedation protocol is an effective procedure to reduce the total doses of benzodiazepines and occurrence of withdrawal symptoms in postsurgical children, which are naïve to opioids or benzodiazepines.

A nurse-driven protocol for analgesia and sedation of children with extracorporeal life support is feasible. Patients with extracorporeal life support do not need deeper sedation levels and have not higher cumulative sedation requirements than children without extracorporeal life support.

Following RBC transfusion, cerebral oxygen saturation increases and cerebral fractional tissue oxygen extraction decreases. The data suggest that cerebral oxygenation in postoperative infants with cerebral fractional tissue oxygen extraction greater than or equal to 0.4 may be at risk in instable hemodynamic or respiratory situations.

Drug rotation with ketamine in mechanically ventilated children with opioid tolerance is feasible and seems to reduce the rate of fentanyl infusion.

The integrity of AR seems to play the same fundamental role after TBI in the pediatric population as in adults and should be determined routinely. It carries an important prognostic value. PRx seems to be an ideal candidate parameter to guide treatment in the sense of optimizing CPP, aiming at improvement of cerebrovascular autoregulation (CPPopt concept).

Little is known about which paediatric patients respond to hydrocortisone rescue therapy (HRT) with improvement of haemodynamic stability in refractory hypotension after cardiopulmonal bypass. Data were gathered retrospectively from children who received HRT in refractory hypotension after cardiopulmonary bypass in the period from 2000 to 2010. One hundred and sixty-six out of 1,273 children, 150 <1 year and 16 >1 year were enrolled. HRT improved haemodynamics significantly, increased blood pressure, decreased the vasoactive-inotropic score and plasma lactate concentrations in all children >1 year and in 82 % (123 out of 150) of the infants <1 year. Non-responders <1 year were significantly younger, lighter, mostly male infants and had longer cardiopulmonary bypass support time. Serum lactate and paediatric risk of mortality score were significantly higher in non-responders at time of initiation of HRT. Mortality was significantly higher in non-responders versus responders (2.44 vs. 13.5 %; p = 0.0008). HRT caused no adverse effects like electrolyte disturbances or hyperglycaemia. HRT in refractory hypotension after paediatric cardiac surgery is safe but not all infants <1 year show haemodynamic response to HRT. Non-response to HRT is associated with significantly higher mortality.
