45
Q

intraperitoneal

46
Q

what is the function of the gallbladder?

A

concentrate and store bile which is produced by the liver

47
Q

what is bile released in response to?

A

cholecystokinin

48
Q

what are the 3 parts of the gallbladder?

A

Fundus – the rounded, distal portion of the gallbladder. It projects into the inferior surface of the liver in the mid-clavicular line.
Body – the largest part of the gallbladder. It lies adjacent to the posteroinferior aspect of the liver, transverse colon and superior part of the duodenum.
Neck – the gallbladder tapers to become continuous with the cystic duct, leading into the biliary tree. The neck contains a mucosal fold, known as Hartmann’s Pouch. This is a common location for gallstones to become lodged, causing cholestasis.

49
Q

tail

56
Q

what vessels travels under the neck of the pancreas?

A

superior mesinteric vessels

57
Q

what arteries supply the pancreas?

A

pancreatic branches of the splenic artery

58
Q

what is the venous drainage of the pancreas?

A

Venous drainage of the head of the pancreas is into the superior mesenteric branches of the hepatic portal vein.
The pancreatic veins draining the rest of the pancreas do so via the splenic vein.

A

common bile duct .: no bile can travel at all

68
Q

what factors can make a patient higher risk for surgery?

A

obesity = harder to safely administer anaesthesia
age = anaesthesia side effects
smoking
sleep apnoea
diabetes = stress of surgery increases blood sugar, fasting may lead to hypoglycaemia

69
Q

what factors make anaesthesia riskier?

A
  • Allergies to anaesthesia or a history of adverse reactions to anaesthesia
    • Diabetes
    • Heart disease (angina, valve disease, heart failure, or a previous heart attack)
    • High BP
    • Kidney problems
    • Lung conditions (asthma and COPD)
    • Stroke
      Seizures
70
Q

what are common adverse effects of general anaesthesia?

A

N+V
sore throat
shock
bleeding
wound infection
DVT/PE
lung problems
urinary retention

71
Q

what are some significant risks of general anaesthesia?

A
  • Accidental awareness (waking during the anaesthetic)
    • Aspiration
    • Dental injury, mainly when the laryngoscope is used for intubation
    • Anaphylaxis
    • Cardiovascular events (e.g., myocardial infarction, stroke and arrhythmias)
    • Malignant hyperthermia (rare)
    • Death
72
Q

what is malignant hyperthermia?

A

Increased body temperature (hyperthermia)
Increased carbon dioxide production
Tachycardia
Muscle rigidity
Acidosis
Hyperkalaemia

hypermetabolic response to anaesthesia

73
Q

how is malignant hyperthermia treated?

A

dantrolene
interrupts the muscle rigidity and hypermetabolism by interfering with the movement of calcium ions in skeletal muscle.

74
Q

how do you perform a nutritional assessment?

A

ABCDE
Anthropemetry = measurements for different components of the body
Biochemistry = blood tests
Clinical = symptoms theyre feeling and comorbidities
Diet = energy, fluid and dietary requirements
Environment = social and physical factors

75
Q

what is rapid sequence induction/intubation?

A

used to gain control over the airway as quickly and safely as possible where a patient is intubated in an emergency scenario and detailed pre-planning is not possible.

It is also used in non-emergency situations where the airway needs to be secured quickly to avoid aspiration, such as in patients with gastro-oesophageal reflux or pregnancy.

76
Q

what is the triad of general anaesthesia?

A

hypnosis = used to make the patient unconscious. They can be either given intravenously or by inhalation.

muscle relaxation = block the neuromuscular junction from working. Acetylcholine (the neurotransmitter) is released by the axon but is blocked from stimulating a response from the muscle. Muscle relaxants are given to relax and paralyse the muscles. This makes intubation and surgery easier.

analgesia

77
Q

what are the options for IV and inhaled hypnotic agents in general anaesthesia?

A

Intravenous options for a general anaesthetic include:
* Propofol (the most commonly used)
* Ketamine
* Thiopental sodium (less common)
* Etomidate (rarely used)

Inhaled options for a general anaesthetic include:
* Sevoflurane (the most commonly used)
* Desflurane (less favourable as bad for the environment)
* Isoflurane (very rarely used)
* Nitrous oxide (combined with other anaesthetic medications – may be used for gas induction in children)

78
Q

what are the 2 categories of muscle relaxants used in general anaesthesia?

A
  • Depolarising (e.g., suxamethonium)
    Non-depolarising (e.g., rocuronium and atracurium)
79
Q

what types of nutritional support techniques are there?

A
  1. Food fortification- adding nutrients to food
    1. Total enteral tube feeding- NG tube
  2. Parenteral nutrition- Delivery of nutrition into the blood stream
80
