The common intravenous anesthetic agent, propofol, is frequently reported to have negative inotropic and chronotropic effects. In the pediatric population, propofol is commonly used after inhalation induction to facilitate endotracheal intubation without the need for a neuromuscular blocking drug agent. In this setting, we have noted that propofol administration is commonly followed by tachycardia. The current study prospective evaluates heart rate and blood pressure changes following the administration of propofol to pediatric patients anesthetized with nitrous oxide (N2O) and sevoflurane. ⋯ Tachycardia following propofol administration occurs in approximately 50% of pediatric patients despite preceding inhalation induction and concurrent administration of N2O and sevoflurane. Future studies are needed to define the mechanism for this effect.

The aim of this study was to explore the risk factors, clinical symptoms, hematological parameters, causative pathogen and antibiotic susceptibility of neonatal sepsis in a Chinese NICU. ⋯ PICC is a bigger risk factor for neonatal late-onset sepsis. Staphylococcus epidermidis was the leading pathogen present in neonatal sepsis in a tertiary maternal & child care hospital in southern China. Vancomycin, teicoplanin and linezolid may be the best choice to management of neonatal sepsis.

In the pediatric hematology-oncology population, lumbar punctures (LP's) are commonly performed to administer intrathecal chemotherapy and obtain CSF samples. Difficult LP's can arise due to obesity, fibrous tissue formation due to repeated LP procedures, or spinal abnormalities. For difficult LP's that require imaging-guidance, fluoroscopy is generally?? Fluoroscopy, however, subjects the patient and healthcare providers to radiation while also potentially increasing procedure cost and time. ⋯ Our preliminary data suggests that ultrasound may be an efficacious alternative to fluoroscopy. By using ultrasound to identify the landmarks in the lumbar region, the appropriate puncture point can be determined allowing access to the intrathecal space with relative ease. This would decrease the need for fluoroscopy-guidance, the incidence of multiple punctures as well as reducing the procedure time and costs.

There is some disagreement about whether the PetCO2 is reliable in predicting the PaCO2 in laparoscopic procedures with CO2 inflation. The aim of the present study is to measure the Pa-etCO2 differences over time in healthy patients undergoing gynecological laparoscopic surgery with different ventilation methods. ⋯ Oxygen concentration and positive end-expiratory pressure could affect Pa-etCO2 in laparoscopic surgery patients.

Several studies documented persistent hypothermia in parturients after spinal anesthesia, while others reported that labor analgesia was related to a high incidence of fever. Continuous spinal labor anesthesia with sufentanil (CSLAS) is a new effective technique in labor analgesia but whether it affects maternal temperature has not been clarified. The aim of our study was to explore the relationship between CSLAS and maternal intrapartum temperature during vaginal delivery. ⋯ The technique of continuous sufentanil spinal labor anesthesia is a safe and effective method in labor analgesia; however, it is associated with an increased incidence of maternal fever.
