what aspects are assessed prior to sedation?
thorough MH
thorough SH
airway assessment
height
weight

SP02
How is airway assessed prior to sedation?
neck size/ posture/ Mallampati score
what is a thorough SH for sedation assessment?
do they have an escort?
how are they travelling?
have they got children who need to be looked after?
the escort can only look after the sedated pt, no one else
when is the Mallampati score used?
anaesthetists use when intubating patients
what is ASA?
assessment of medical fitness for sedation
(American Society of Anesthesiologists)
classification based on physical status
allocation of pt to grades according to: medical status, operative/ anaesthetic risk
an estimation of fitness for sedation or GA
what are the ASA classifications?
ASA1 - a pt without systemic disease, a normal healthy pt
ASA2 - a pt with mild systemic disease (mild asthma etc)
ASA3 - a pt with moderate systemic disease, which limits activity but is not incapacitating (more severe asthma etc)
ASA4 - a pt with incapacitating systemic disease, which is a constant threat to life (severe angina etc)
ASA5 - moribund pt not expected to survive 24 hours unless treated
what are the 2 numbers for BP?
systolic/ diastolic
measured in mm Hg
what is systolic pressure?
in arteries when the heart beats
what is diastolic pressure?
in arteries between heart beats (heart resting)
what is white coat hypertension?
high BP because nervous in medical setting
what is the BP readings for ASA 1 and 2?
ASA1 = <140/90
ASA 2 = <160/95
what are the BP readings for ASA 3 and 4?
ASA 3 = <200/115
ASA 4 = >200/115
what is the cut off for BP to get IV sedation in general dental practice?
> 160/95
(DDH = 170/100)
how is BMI calculated?
weight (kg)/ height (cm) squared
what is oxygen saturation?
percentage of haemoglobin which is bound to oxygen
how is oxygen saturation measured?
pulse oximeter
- measures the ratio of infra red light to red light (want it to be as close to 100 as possible)
what is involved in the pre-sedation assessment?
DH
sedation/ GA history
dental tx plan
selected conscious sedation technique
any individual pt requirements
provision of pre and post op written instruction provided before tx
what is included in the pre sedation form which starts the consent process?
name of procedure and course of tx
site/ side surgery
intended benefits
