Causes of Acute kidney injury (AKI)

By -

 Pre - renal conditions:

  • Hypovolemia, Hemorrhage, Dehydration 
  • Low cardiac state - acute or chronic heart failure
  • Vasodilatory hypotension - sepsis 
  • Chronic liver disease 
  • Abdominal compartment syndrome 
  • Medications - ACEI, ARB, NSAIDs, Radiocontrast agents 
 Intrinsic renal disease:

  • Acute tubular injury 
  • Autoimmune - 
    • Glomerulonephritis 
    • Interstitial nephritis 
    • Vasculitis 
  • Inflammatory - 
    • Systemic inflammation 
    • Sepsis 
    • Rhabdomyolysis, Crash injury, Burn 
    • Major surgery
    • Cardiopulmonary bypass 
  • Metabolic - 
    • Hypercalcemia 
    • Hyperuricemia
Post renal conditions: 

  • Prostatic hypertrophy 
  • Nephrolithiasis 
  • Bladder tumor 
  • Pelvic mass

Monitoring neuromuscular block

Following stimulation of the relevant nerve. Nerve stimulators must generate a supramaximal stimulus (60–80 mA) to ensure that all the composite nerve fibres are depolarized. Duration 0.1 ms. Negative electrode directly over the nerve. Positive electrode  placed where it cannot affect the muscle in question. Five main patterns of stimulation Single twitch stimulation Simplest form Requires a baseline twitch height Reduction in twitch height observed until 75% of NMJ receptors have been occupied by muscle relaxant  Only a small number of receptors are required to generate a summated mini end-plate potential, which triggers an action potential Partial NMJ block with depolarizing muscle relaxants (DMRs) and non-depolarizing muscle relaxants (NDMRs) reduce the height of single twitch stimulation. Tetanic stimulation Individual stimuli are applied at a frequency >30 Hz Twitches observed in the muscle become fused into a sustained muscle contraction – tetany Most stimulators deliver stimu

Regulation of Hepatic blood flow

By -
  Blood supply of liver  25% of cardiac output, 1.5 L/ min Blood supply by hepatic artery (1/3 supply, 98% O2 saturation) and hepatic portal vein (2/3 supply, 70 - 85% O2 saturation) The hepatic triad is formed by the branches of the hepatic artery, hepatic portal vein and bile canaliculus which run together  Portal venue and hepatic arteriole join together to form hepatic sinusoid (specialised capillary system) which optimises exchange with hepatocyte  Venous drainage to IVC via right and left hepatic vein  Regulation of hepatic blood flow  Hepatic artery - extrinsic and intrinsic regulation mechanism  Portal vein - extrinsic regulation  mechanism  Intrinsic mechanism:  Myogenic autoregulation 👉🏻 if drop-in hepatic arterial pressure ➡️ flow is maintained by a decrease in hepatic arterial resistance  Hepatic arterial buffer response 👉🏻 if reduction of flow in portal vein ➡️ compensatory decrease in resistance of hepatic artery to increase arterial blood flow  Extrinsic mechanism: S
