Expect the Unexpected
Neonatal Oral Mass Diagnosed at Birth

 Anesthesiology May 2013

A full-term, 3.5-kg neonate was transferred for management of a large, mobile intraoral mass. The infant demonstrated no signs of airway obstruction or respiratory  distress and had normal oxygen saturation without support. The child did not seem dysmorphic and the mass was isolated  to the anterior maxillary alveolar ridge, easily mobilized out of mouth. A prenatal ultrasound at 20 weeks did not identify any anomalies. Adequate ventilation was achieved after mobilizing the mass extraorally and achieving adequate mask seal. At this point, a mask induction with spontaneous ventilation was performed, followed by uneventful intubation. The mass was considered low risk for airway obstruction during induction  because it did not disturb the airway anatomy, and was easily mobilized out of the mouth. Epulis, or congential granular cell tumor, is a rare tumor of variable size and number originating from gingival epithelial tissue seen in newborn infants, affecting female infants 8:1, and is rarely malignant.


Differential diagnosis for neonatal oral masses includes teratoma, hemangioma, lymphatic malformation, or congenital malformation or neoplasm.
 When diagnosed prenatally, consideration for airway obstruction  at birth may require intervention upon delivery. However, prenatal diagnosis is not always achieved. Considerations before induction of anesthesia focus on the anatomic location of the mass, distortion or obstruction of the airway, and signs of airway obstruction. Although computed tomography or magnetic resonance imaging studies may yield information about airway involvement, the infant may require an airway intervention before or during the study.

power injectable peripherally inserted central catheters

Clinical experience with power injectable peripherally inserted central catheters in intensive care patients     Introduction In intensive care units (ICU), peripherally inserted central catheters (PICC) may be an alternative option to standard central venous catheters, particularly in patients with coagulation disorders or at high risk for infection. Some limits of PICCs (such as low flow rates) may be overcome by the use of power-injectable catheters . Method We have retrospectively reviewed all the power injectable PICCs inserted in adult and pediatric patients in the ICU during a 12-month period, focusing on the rate of complications at insertion and during maintenance. Results We have collected 89 power injectable PICCs (in adults and in children), both multiple and single lumen. All insertions were successful. There were no major complications at insertion and no episodes of catheter-related blood stream infection. Non-infective complications ...

Things to Avoid in Anesthesia for Pregnant with Pulmonary hypertension

Anesthesia for Pregnant woman with Pulmonary Hypertension is a real challenge for anesthesiologist. It is very crucial to remember the pathophysiology of pulmonary hypertension in pregnant women and to avoid some practices that will worsen the cardiac status. 1-Avoid single shot spinal anesthesia. Some authorities consider pulmonary hypertension as absolute contraindication for single shot spinal anesthesia specially in patients with NYHA III ,IV. Spinal anesthesia causes major hemodynamic instability(decrease SVR, decrease VR, decrease in CO) The preferred neuroaxial techniques are (epidural anesthesia and CSE with minimal spinal dose) 2-Avoid PAC. Pulmonary Artery catheters insertion may lead to pulmonary artery rupture or thrombosis. TEE is better cardiac monitor/Arteial line is mandatory. 3-Avoid Nitrous oxide in gas mixture.N2O increase the PVR 4-If MV to be started, avoid High TV and PEEP 5-Avoid Oxytocin Boluses, or rapid administration of Pitocin. Oxytocin causes ...

The 12 decision making steps for post dural puncture headache treatment

Treatment decision-making algorithm for postdural puncture headache. 1. When diagnosis is made, all patients should receive supportive measures (reassurance, bed rest, analgesics, hydration, quiet environment). 2. Severity of symptoms should be classified using VAS scale (mild 1–3, moderate 4–6, severe 7–10). 3. Virtually all patients will improve in time even without additional therapy. (dashed lines) 4. Symptoms worsen or fail to resolve within 5 days. 5. Patient preference dictates the choice between pharmacologic (less effective) and epidural blood patch (EBP). 6. In patients with severe symptoms, EBP is strongly suggested. 7. The most common pharmacologic measure is  caffeine  prescription. 8. The failure, worsening, or recurrence of symptoms after pharmacologic measures favors the use of EBP. 9. In addition to EBP, other epidural treatment options can be considered in select patients (eg,  dextran , saline). 10. A period of 24 h should lapse before repeating EBP. 11...
