Have you ever thought of spinal/epidural in Dwarf pregnant



When you go to do neuro- axial block in Dwarf pregnant remember the following  10 points:

1-Dwarf patients have higher incidence of pelvic deformities,  they have higher incidence of C/S...so prepare yourself for shift from NVD to CS

2-Many dwarf patients suffer from pulmonary compromise, so they may not tolerate supine position while awake, and they may not tolerate the fluid preloading. Fluids should be given cautiously rather than large predetermined volumes. Patient with severe pulmonary compromise should be intubated.

3-Airway is Big problem in Dwarfs. They Have difficult airway (large occiput,atlantoaxial instability) and higher incidence of aspiration(BIG uterus in small abdominal cavity).So choose elective intubation rather spinal anesthesia if  you feel that patient airway will bring troubles.

4-Vertebral column is part of musculo-skeletal deformities. They have higher incidence of spinal stenosis, and difficult spaces, and surely have higher incidence of patchy epidurals...tell the patient ,"epidural may not work" and "many attempts may take place".

5-Smaller epidural space. Which mean higher incidence of wet tap..............go slowly

6-one shot spinal for C/S is not good choice...read 7 to know why

7-There is no dosage guideline for patients with short stature and abnormal spinal anatomy. With single shot spinal fears of over dosage may lead to inadequate analgesia and intraoperative discomfort ,while over dosage may lead to high spinal or total spinal. The better option is mentioned in the next point.

8-Epiural to be placed then augmented according to the anesthesia level is the better option, with careful increment of  dosage. And always prepare yourself for GA since failed block may occur....prepare the glidoscope and fiberoptic..."difficult airway"

9-Epidural Test dose may result in High spinal if the catheter was intrathecal. Again there is no clear guidelines, decreasing the dose may lead to false negative results. Giving the regular dose in divided fashion may solve this controversy.

10-Remeber GA and Regional are hazardous. Management plan should be always individualized

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 ...

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 ...

Lumbar and thoracic epidural in Pediatrics-Technical aspect

The midline approach is most commonly used. The ligamentum   flavum is considerably thinner and less dense in infants than in older children and adults. This makes recognition of engagement in the ligament more difficult and requires both extra care and slower, more deliberate passage of the needle to avoid subarachnoid puncture. The angle of approach to the epidural space is slightly more perpendicular to the plane of the back than in older children and adults, owing to the orientation of the spinous   processes in infants and small children. The loss of resistance technique should be used, but only with saline, not air. There are several reports of venous air embolism in infants and children when air was used to test for loss of resistance Use a short (5 cm) 18-gauge Tuohy needle and a 20- or 21-gauge catheter in infants and children. Epidural kits specifically for infants and children are available Maximum of 0.4 mg/kg/hr of bupivacaine after the initial block is estab...
