  • On post partum day 1 neonate is oligouric followed by diuresis and natriuresis also resulting in weight loss. The diuresis is regardless of the fluid intake
  • Transcript

    • 1. Dr. Ravi Prakash Kanojia Assistant ProfessorDept of Paediatric Surgery PGIMER CME: Anaesthesia for neonatal surgical emergencies: Pearls & Pitfalls
    • 2. Neonatal surgical emergencies Common cases Emergencies Semi -Emergencies  Congenital diaphragmatic  Bladder exstrophy hernia  Hirschsprungs  Tracheoesophageal fistula  Neural tube defects  Anorectal malformation  Obstructive uropathies -  Intestinal atresias PUV  Malrotation
    • 3. What does the surgeon wants in the neonate before starting for surgery (pt optimization) What does the surgeons expects from the anaesthetist SurgeonsPerspectives
    • 4. What does the surgeon wants in the neonatebefore starting for surgery (pt optimization)
    • 5. How do we define preoperativestabilisation (optimisation) Neonate is  Normothermic  Normal hydration and electrolyte  No acid base disturbance  Adequate renal and respiratory function
    • 6. What does the surgeon wants in the neonatebefore starting for surgery (pt optimization) Before embarking on the surgery the baby needs to be stabilized on various parameters and aspects  Temperature control  Fluid balance  Blood gasses  Urine output  Identifications of decompensate systems like hypoplastic lungs, cardiac shunts, dysplastic kidneys  Specific condition related requirements
    • 7. Identification optimisation strategy
    • 8. FluidIdentify Optimize The physiological shifts Balance early natriuresis occurring during first 48 and diuresis by fluid hours of life The ongoing fluid losses via • Nasogastric aspirates • Loss through respiratory tract • Evaporative losses by exposed Image mucosa/ epithelial surfaces eg gastroschisis • renal loss – Post obstructive diuresis in obstructive uropathies like PUV
    • 9. Temperature control • Inherent • Active propensity to warming hypothermia • Avoid • Temperature loss due to exposed unnecessary Identify surfaces Optimize exposuretemperature • Hypothermia due Thermore • Cotton wraps loss and its to long surgery gulation • Coveringconsequence • Hypothermia exposed induces acidosis by viscera
    • 10. Blood gases • Respiratory system • Metabolic disease – CDH acidosis • Uropathies – • Treatment of PH Is inadequate renal shock buffer – PUV,altered dysplastic kidneys Corrections • Correction of in • Intestinal volume and obstruction with electrolyte loss of ions and deficit bicarbonate • Alkali therapy
    • 11. Sepsis & Antibiotics Infection and Sepsis go hand  Recognise sepsis  Indirect method in hand with surgical  Refusal to suck conditions  Poor cry  Often compounded by  Lethargic ventilation, surgical site  Poor capillary refill time infection & nosocomial  Abdominal distension component  Low urine out put  Fever / hypothermia  Most common organism in  Tachypnea our settings are  Direct method  E coli  Positive culture from blood urine csf  Staph aureus  Raised CRP  Klebsiella  Leucopenia  Fungal  Neutropenia
    • 12. Antibiotics Know the bug Know the susceptibility (or likely susceptibility) Identify the site of infection Host Factors In vitro response is not the same as in vivo
    • 13. Identify
    • 14. Antibiotic choiceType of infection Expected pathogen First choice 2nd choiceIntra-abdominal S Aureus, e coli Ceftriaxone Imipenum ,infection Kleibsiella, cefotaxime meropenum enterococci Ampi-sulbactum Piperacillin tazobactumCNS infection S Aureus, S Ceftriaxone Vancomycin Epididermis cefotaxime Meropenum PseudomonasBiliary tract E coli, enterococci , Cefoperazone – Imipenum ,infection kliebsiella , sulbactum , meropenum clostridium perfringesGentamicin/ Amika for enterobacter, pseudomonas & S epididermisVancomycin for coag neg staph/MRSAMetronidazole if anerobes are suspected (liver abscess). Fluconazole for yeast
    • 15. Transport (journey in & out of OR) Temperature controlTransport Care ofteam and drains and vehicle tubes Neonatal transport Monitoring Respiratory on the move assistance
    • 16. What does the surgeon expects from the (Neonatal)Anaesthetist
    • 17. What does the surgeon expects from the (Neonatal)Anaesthetist A dedicated neonatal anaesthetist Dynamics of neonatal physiology Know the condition  The abnormal anatomy  The compromised systems  CDH – Respiratory  PUV – renal  Hydrocephalus – CNS  Impact of the condition on the tolerance of anaesthesia
    • 18. Stabilisation in individual conditionsrequiring emergency neonatal surgery  Tracheoesophageal fistula  Frequent suction to avoid aspiration  As far a possible avoid intubation and mask ventilation  Causes stomach distension  If intubation is required try to place the bevel of tube away from fistula to the left  Avoid excessive positive pressure
    • 19.  Congenital diaphragmatic hernia  No bag mask  Early intubation  High frequency ventilation  Optimisation of arterial blood gasses GIT atresia  ARM – single stage repair in prone position  Intestinal atresias – nasogastric loses / resection of bowel – short bowel
    • 20. Understanding the urgency in theemergency Malrotation (with volvulus)  Understand the urgency of the condition and impending gangrene Hirschsprungs  Intestines can be decompressed by rectal washes but sub acute obstruction still persists and delay increases the chances of enterocolitis and sepsis Spina Bifida – thin membranes over swelling, impending rupture and meningitis waiting to happen
    • 21. Surgeon’s message Neonatal emergency surgery requires highest level of scientific precision when it comes to manage and needs experience by a full time neonatal anaesthetist well versed by the dynamic physiology and pathology Identification – optimisation strategy Normothermic, hydrated baby with no electrolyte and acid base disorder is the basic requirement which will improve outcome. Understanding the disease anatomy and specific morbidity factors will save the baby
