a) Difficulty in suction due to bend
b) Fixed length from bend: frequently advance down right main bronchus

c) High pressure, low volume cuff

4) Protocol for endotracheal intubation in ICU

A) Personnel: Intubation is a 4 person procedure; skilled assistance is mandatory:

I) "Top end" intubator who co-ordinates the intubation
II) One person to administer drugs

III) One person to apply cricoid pressure once induction commences:

a) This is recommended as a routine for emergency intubations
b) The intubator should direct the person who is applying cricoid pressure so that pressure is correctly applied and removed if distortion of the larynx or difficulty in intubation occurs as a result of cricoid pressure.

IV) One person to provide in line cervical spine immobilisation (trauma and spinal patients only)

B) Secure adequate IV access

H) Cuff checks

I) Volumetric (sufficient air to obtain a seal + 1 ml) tests are done following insertion and whenever a leak is detected with a manual hyperinflation once per nursing shift.
II) Seal is assessed by auscultation over trachea during normal ventilation.

III) Manometric tests are inaccurate and do not correlate with mucosal pressure. These are an adjunct only if cuff malfunction is suspected.

I) Persistent cuff leaks

I) Tubes requiring more than 5ml of air to obtain a seal or if there is a persistent cuff leak must be examined by direct laryngoscopy as soon as possible even if the tube appears to be taped at the correct distance at the teeth.
II) Ensure that:

a) The cuff has not herniated above the cords
b) Tube has not ballooned inside the oral cavity and "pulled' the cuff above the cords.

III) High risk patients for cuff leaks:

a) Inappropriately cut tubes: do not cut tubes < 26 cm
b) Facial swelling (burns, facial trauma)

c) Patients requiring high airway pressures during ventilation

5) Endotracheal tube change protocol

A) Ensure adequate skilled assistance, equipment, drugs and monitoring as for de novo intubation.
B) Procedure

II) Ensure sufficient anaesthesia and muscle relaxation (fentanyl / propofol + neuromuscular blockade)

C) Perform laryngoscopy and carefully identify patency of upper airway after suction, anatomy of larynx, degree of laryngeal exposure and swelling.

I) Clear view of larynx and no or minimal laryngeal swelling:

a) Application of cricoid pressure by assistant and careful, graded extubation under direct laryngoscopic vision.
b) Maintain laryngoscopy and replace tube under direct vision.

II) Impaired visualisation of larynx:

a) Use gum elastic or ventilating bougie
b) Place bougie through tube under direct vision and insert to a length that would be just distal to the end of the ETT (approximately 30cm from end of tube)

c) Have an assistant control the bougie so that it does not move during movement of the endotracheal tube

III) Application of cricoid pressure by assistant and careful, graded extubation
IV) Maintain laryngoscopy and ensure bougie is through the cords on extubation

V) Replace tube over bougie and guide through larynx under available vision.

B) Confirmation of pericardial effusion or tamponade must be made with echocardiography prior to procedure. Liaison with cardiology is essential.

2) Indications

A) Symptomatic pericardial effusion (tamponade).
B) Although advocated in EMST, this procedure has limited utility in traumatic pericardial tamponade.

3) Procedure

A) Strict aseptic technique.
B) Local anaesthetic infiltration if awake patient.

C) This procedure is greatly facilitated using echocardiography guidance

D) Technique: Seldinger technique and insertion of a pigtail catheter

I) Small incision under xiphisternum
II) Insert needle on syringe at 45 o from the horizontal axis and aim for tip of left shoulder

III) Advance slowly and aspirate until confirmation by aspirating blood or serous fluid

IV) Insert catheter using Seldinger technique over guidewire.

V) Confirm placement by aspiration and/or echocardiography

E) Check CXR (pneumothorax)
F) Suture and occlusive dressing if leaving for > 24 hours.

4) Complications

A) Arrhythmias
B) Cardiac tamponade!

C) Myocardial laceration

D) Pneumothorax, pneumopericardium

E) Liver laceration

Transvenous pacing

Types Arrow Bipolar Electrode Catheter 5 Fr 110cm

1) Policy:

A) The decision to insert a pacing wire is by the duty ICU consultant.
B) If inserted by ICU staff, the procedure is only to be performed by consultant staff or advanced vocational trainees under supervision.

C) Become familiar with the theory of insertion, indications, interpretation and complications of TVP.

2) Indications :

A) Medical pacing with adrenaline or transthoracic pacing is usually adequate to treat the majority of symptomatic bradycardias.
B) Symptomatic bradycardias:

I) Complete heart block
II) Bifascicular block in association with evolving (especially anterior) myocardial infarction

III) Severe beta blocker poisoning

IV) "Trifascicular" block in high-risk patients.

C) Following cardiac surgery in high-risk patients:

I) Valve replacement / repair: especially mitral
II) VSD repair / papillary muscle rupture

III) Acute myocardial infarction

D) Persistent A-V block may benefit from sequential pacing: this is done by cardiology
E) Tacharrhythmias

I) Ventricular tachycardias (especially polyphasic) may respond to overdrive suppression pacing.

3) Types

A) Bipolar pacing lead (VVI): insert under image intensification (standard TVP at RPAH)
B) Balloon flotation leads: may be inserted under ECG guidance

C) Paceport PA catheters: these have little utility.

D) Epicardial leads: placed during cardiac surgery in high risk patients these are usually unipolar ventricular, but may be bipolar, atrial or ventricular: check operative note and liaise with the surgeon.

4) Procedure protocol: (VVI lead)

I) This is preformed by cardiology in the cardiac catheterisation laboratory.

5) Floatation Catheter Insertion

A) Catheters

I) Cook bipolar pacing kit, 6Fr ballon tipped.
II) Arrow bipolar ballon electrode catheter.

B) These may be inserted either "blind", under ECG guidance (standard recommendation), or via pressure guidance for catheters having an infusion lumen (cf. PA catheter insertion).
C) Aseptic technique & local anaesthesia where appropriate

D) Insertion protocol:

I) 6F X 15.5 cm introducer (Cook), do not use a PAC introducer (8Fr) as these will leak
II) Attach V5 lead of an ECG to the distal electrode of catheter & monitor

III) Note P then QRS wave-form changes as the catheter advances to the RV

IV) Advance catheter another 2cm, deflate the balloon & advance 1cm

V) Connect to the pulse generator (switched off)

VI) Set output and sense to their minimum value, and rate 20 bpm faster than the patient's own rate.

VII) Turn the generator on and gradually increase output while watching the ECG for capture.

VIII) If there is no capture or a high output is required

a) Place on demand mode
b) Turn output right down

c) Advance or reposition the wire slightly

d) Try to capture again

e) An ideal capture setting is ~2 mA

IX) Suture wire and apply an occlusive dressing
X) Post insertion CXR.

Oesophageal tamponade tubes

1) Policy:

A) All patients with tamponade tubes should be intubated prior to insertion and managed in Intensive Care.
B) As a result, ICU staff may be requested to insert oesophageal tamponade tubes for acute upper GI bleeding.

C) The decision to insert a tube is made in conjunction with the gastroenterologist. There are a number of tamponade tubes available: ensure that the operation, balloon inflations are discussed with the gastroenterologist.

D) Become familiar with the theory of insertion, indications, and complications of these tubes.

2) Indications :

A) Variceal haemorrhage
B) Where endoscopy cannot be done due to bleeding

C) Failure of sclerotherapy, banding and/or octreotide.

3) Types of tubes:

A) Minnesota: oesophageal and gastric balloons and aspirating catheters
B) Sengstaken: oesophageal and gastric balloons and gastric catheter
16F, 20 F.
C) Linton: gastric balloon and catheter

4) Procedure:

A) Check both balloons for leaks before insertion.
B) Inflate the gastric balloon with 300ml of air and check pressure reading.

C) Deflate all balloons completely and lubricate the tube

D) Insert well in under direct vision using a laryngoscope then x-ray to ensure the tube is not folded up in the oesophagus (inflating the gastric balloon in the oesophagus is virtually 100% fatal!)

E) Inflate the gastric balloon with 300 ml of air, then pull back until resistance is felt as the balloon rests against the gastric fundus.

F) Check the pressure in the gastric balloon: this should not exceed the pre-insertion pressure by > 5mmHg if the gastric balloon is correctly placed in the stomach: higher pressures suggest incorrect (ie oesophageal) placement. If high pressures are evident, deflate the balloon, reinsert and check on x-ray.

G) Note the measurement at the lips, and fix securely with gentle traction:

I) Rope and pulley system with 500 ml bag of fluid, or
II) Adhesive tape to face.

H) Connect a pressure gauge to the oesophageal balloon, and inflate to a pressure of 40 mmHg. (inflation of the oesophageal balloon may not be required)
I) Recheck position on x-ray.

J) After 12-24 hours, the balloons should be let down and if bleeding does not recur the tube may be removed (liaise with the gastroenterologist).

K) Sclerotherapy is usually performed: (50% patients will re-bleed otherwise.)
