Study Notes
Clinical Reasoning
- Integrate clinical and contextual factors to make diagnostic and treatment decisions.
- Pattern recognition, intuition, more error-prone.
- Problem-solving approach: system, location, lesion.
Surgical Procedures
- SOAP (Subjective, Objective, Assessment, Plan) for procedure documentation.
- Important Surgical Principles: THA (Tissue Handling Approach), TAPE (Tissue handling, assessment, preserving blood supply, eliminating dead spaces, accurate tissue apposition, tension-free), HEAP (History, Exam, Assessment)
Pharmacology
- International Non-proprietary Names (INN) are used as generic names for drugs.
- Classification of drugs by properties (physiochemical, mechanism of action [MoA]).
- Prescription involves patient assessment for diagnosis, prescribing according to the identified diagnoses.
- Drug absorption is dependent on properties such as solubility, hydrophobicity, and diffusion.
- Drug distribution is related to plasma proteins (bound to protein or free), and distribution between body compartments.
- Drug metabolism changes drug structure to be more readily excreted.
- First-pass effect (drug is first metabolised by liver or gut) before reaching the systemic circulation.
- Drugs are eliminated through metabolism and excretion by the kidneys, liver, and other pathways.
Pharmacodynamics
- Drug-target interaction modulates biological function/effect.
- Structure-activity relationship (SAR) describes relationship between drug structure and its biological effect.
- Direct action: acts directly on target. Indirect action: drug acts upon a different target (sometimes endogenous release, inhibiting endogenous reuptake/metabolism)
- Agonist acts like a signal (stimulates).
- Antagonist blocks a signal (prevents)
- Dose/concentration-response relationship demonstrates the relationship between dose/concentration and the magnitude of effect of a drug, resulting in sigmoidal curve.
- Drug potency refers to the amount of drug required to exert a defined effect.
- Drug selectivity relates to the ability of the drug to only target the desired target.
- ADRs denote adverse drug reactions of a drug, type A = dose-dependent
- Therapeutic index (TI) relates dose of a drug that causes toxicity to the dose that elicits a therapeutic effect
Pharmacokinetics
- Drug clearance depends on factors such as drug concentration in plasma, total elimination & its bioavailability.
- Steady-state concentration is reached when drug absorption is equal to elimination rates
- First-pass effect: oral drugs are metabolised in the gut and liver.
- Volume of distribution describes the theoretical volume that is needed to dilute the total drug in the body to achieve the measured plasma concentration.
- Bioavailability is the fraction of administered drug that reaches the systemic circulation.
- Kinetic = – Zero order = constant amount for drug given per unit of time – First order= given as a constant fraction of the drug per unit time – Drug elimination half-life = time to reduce drug plasma concentration by 50%.
Clinical Preparation
- Premed (pre-operative medication) to ↓anxiety & catecholamine release and ↓ ANS activation
Anaesthetic Agents
- TIVA (total IV anaesthesia) = simultaneous IV injection & inhalant anaesthetics for maintaining anaesthesia.
- Induction agents rate can influence the rate of the rate of induction
- Ketamine (phencyclidine derivative)= rapid onset, and has dissociative effects
- Propofol = rapid IV induction and emergence
- Etomidate = rapid onset, less CV effects than other induction agents, not for CRI
- Inhalational agents = direct action on body . Oil/gas partition coefficient = anaesthetic potency . MAC (Minimum Alveolar Concentration): concentration of anaesthetic agent at which 50% of patients fail to respond to a noxious stimulus.
Anesthetic Systems & Equipment
- Various anesthetic systems exist = rebreathing vs Non rebreathing
- Gas supply, O2 delivery systems, P regulators/o2 concentrators for low P, & Flowmeters
- Proper use of components to prevent complications
- Understanding of different parts and proper function, & how to troubleshoot, and how to use for care/pre cautions
Surgical Instruments
- Description of different components and their uses – scalpel, scissors, forceps
- Special focus on different types of forceps & scissors (ex. haemostatic forceps, tissue forceps, scissors)
- Appropriate choice based on the tissues being manipulated.
Wound Healing and Management
- Inflammation (0-48hrs), Prolif (days 5-21), and Maturation phase (days 21+)
- Factors affecting wound healing (contamination, location, concurrent trauma, etc)
- Debridement (tissue removal)
- Wound closure methods based on exudate/infection presence
- Appropriate dressings and wound management techniques
- Understanding of different terms (laceration, degloving, abrasion, puncture, contusion, crush)
- Complications with wound healing (infection)
Antibiotics
- Classification of antibiotics based on mechanism of action.
- Indications (Gram +/-, anaerobic) to use ABs
- Time-dependent antibiotics: effectiveness relies on concentration above the minimum inhibitory concentration (MIC)
- Concentration-dependent antibiotics: effectiveness increases proportionally with the difference in concentration above the minimum inhibitory concentration (MIC)
Radiography and Radiation Safety
- X-ray dose management to limit radiation exposure to client & personnel
- Understanding of image qualities, positioning, & artifacts.
Ultrasonography
- Use of sound waves to create images, including probe type(linear array, curved), and limitations
- Interpretation of different imaging findings (e.g. fluid, lesions)
Pain Management
- Importance of assessing and managing pain throughout all surgical care.
- Use of systemic (system-wide pain meds), local, regional, & topical analgesics.
