Slide 3
Which of the following pulmonary effects are associated with increased PaCO₂ during laparoscopy? select 3
a) Decreased FRC
b) Increased PIP
c) Increased FRC
d) Development of atelectasis
a) Decreased FRC - tidal volume drops
b) Increased PIP
d) Development of atelectasis - if you didn’t adjust for hypoventilation
Slide 4
Which of the following statements are true about lung compliance during laparoscopy?
a) It increases by 30-50%
b) It decreases by 30-50%
c) It remains unchanged
d) It contributes to easier lung expansion
b) It decreases by 30-50%
diaphragm cannot drop and lungs cannot expand
Slide 4
How long does it typically take for absorbed PaCO₂ levels to plateau during laparoscopy?
a) 5-10 minutes
b) 10-15 minutes
c) 15-20 minutes
d) 20-25 minutes
b) 10-15 minutes
increased PaCO2 due to absorption of CO2 that plateaus in 10-15 mins
Slide 5
Which factor is considered when deciding on treatment for increased PaCO₂ during laparoscopy? (2)
a) Increase Vm
b) Early case vs. late case
c) Patient’s age
d) Type of anesthetic used
a) Increase Vm
b) Early case vs. late case
Kane: If early on the case and your CO2 at 50-55, you want to adjust that and you want to blow OFF that CO2 ; If towards at end of the case and increase CO2 is more than you’d like to be, you may choose to leave it so pt. will be stimulated to breath
Slide 5
Which of the following are potential pulmonary complications during laparoscopy? (3)
a) Subcutaneous emphysema
b) Pneumothorax
c) Pneumomediastinum
d) Pulmonary edema
a) Subcutaneous emphysema
b) Pneumothorax
c) Pneumomediastinum
possibility can stick trocars through belly and into the chest 🙁
Slide 6
What are pulmonary complications from insufflation during laparoscopic prodecures? (select 3)
a) Gas embolism
b) Endobronchial intubation
c) Pulmonary fibrosis
d) Subcutaneous emphysema
a) Gas embolism
b) Endobronchial intubation
d) Subcutaneous emphysema
Slide 6
What is a common cause of subcutaneous emphysema and pneumothorax during laparoscopy?
a) High intra-abdominal pressure
b) Improper placement of trocars
c) Overuse of anesthesia
d) Patient’s pre-existing conditions
b) Improper placement of trocars
*pneumothorax requires CT
Slide 7
How long does it typically take for subcutaneous emphysema and pneumothorax to resolve?
a) 10-20 minutes
b) 20-30 minutes
c) 30-60 minutes
d) 60-90 minutes
c) 30-60 minutes
Slide 7
Which of the following should be monitored when managing subcutaneous emphysema and pneumothorax? (select 2)
a) Blood pressure
b) Heart rate
c) Ventilation
d) Oxygenation
c) Ventilation
d) Oxygenation
Slide 7
What causes a gas embolism during insufflation?
a) Gas infused directly into the abdominal cavity
b) Gas infused directly into a vessel
c) High oxygen levels
d) Low atmospheric pressure
b) Gas infused directly into a vessel
Kane: In vessel = massive embolism can lose the patient
Slide 8
True or False
A gas lock in the vena cava can enhance venous return.
False
A gas lock in the vena cava can obstruct venous return.
Laparoscopic Surgery
Slide 8
Which cardiac issues are a sign of gas embolism? (4)
a) Atrial fibrillation
b)Tachycardia
c) Hypotension with increased CVP
d) Ventricular hypertrophy
e) Cardiac dysrhythmias
f) Millwheel murmur
b)Tachycardia
c) Hypotension with increased CVP
e) Cardiac dysrhythmias
f) Millwheel murmur
Laparoscopic Surgery
Slide 9
Which of the following are diagnostic signs of gas embolism? (Select 2)
a) Hypoxemia
b) Bradycardia
c) Decreased ETCO₂
d) Hypercapnia
a) Hypoxemia -better seen on ABG
c) Decreased ETCO₂
Laparoscopic Surgery
Slide 9
Which of the following is a common treatment step for gas embolism during laparoscopy?
a) Increase insufflation pressure
b) Cessation of insufflation/release of pneumoperitoneum
c) Initiate CPR
d) Induce hypothermia
b) Cessation of insufflation/release of pneumoperitoneum
Slide 9
Laparoscopic Surgery
Which of the following treatments are appropriate for gas embolism? (Select all that apply)
a) Trendelenburg position
b) Fluid bolus
c) Increase oxygen intake to 100%
d) Aspiration of air
e) Vasopressor support
All of the above
a) Trendelenburg position - put pt. in left lateral tilt with head down -keep bubble in right heart and prevent from going into lungs
b) Fluid bolus
c) Increase oxygen intake to 100%
d) Aspiration of air -if pt has a central line
