    Special patient for local anesthesia Special patient for local anesthesia Presentation Transcript

    • LA Management of Special PtientIyad M.Abou Rabii
    • Patient with Special Needs The usual dental care scenario for those with special needs may involve an uncooperative child. Depending on the level of special needs of the child, and the patience and skill of the dentist, preventive and early restorative care often lack. As the child ages, extensive oral decay, cavities, and infection may occur. The parents of children with autism and other special needs often search for an oral surgeon who may have enough anesthesia training and experience to deeply sedate or do a quick general anesthetic to remove the abscessed tooth or teeth. Through sedation dentistry and general anesthesia, we able to provide top level dental care to patients with special needsPage  2
    • Psychological Preparation Take your time. Although you may be able to perform the dental procedure quickly, the behavior management of the patient often will require more of your time and patience. Do a little of the procedure at a time. Giving the patient time to adjust to the activity at hand allows for desensitization and for an easier appointment next time. Speak the patient’s language. Simple sign-language skills are helpful when working with hearing-impaired or nonverbal clients. Practice show, tell and do. Throughout the appointment, break the procedure down into small steps. At each step, show the patient what you plan to do as you tell him or her about this step; then perform the procedure in stages. Establish a relaxed atmosphere. Communicating in a soft voice and using a gentle touch will go a long way toward helping the patient relax.Page  3
    • Children Children should have a comfortable experience when going to the dentist. Local anesthetics are an important tool for the control of pain and discomfort during dental treatmentPage  4
    • What local anesthetic All local anesthetics have a low margin of safety between the effective dose and the toxic dose. The lethal dose for many local anesthetics is only 3 times that of the effective dose. Deaths following local anesthetic administration are almost always a result of overdosage. The maximum safe dose of lidocaine for a child is 4.5 mg/kg per dental appointment.Page  5
    • What local anesthetic Bupivicaine (Marcaine) is an amide local anesthetic with a high toxic potential, and should not be used in children. The duration of anesthesia with bupivicaine can be as long as 24 hours. Lidocaine is less toxic than many other local anesthetics, because its interactions with the cardiac sodium channel are “fast in – fast out,” whereas a local anesthetic such as bupivicaine is "fast in – slow out.” So the best LA to be used with children is LidocainePage  6
    • What Technique Local infiltration of anesthesia is sufficient for all dental treatment procedures in 90% of cases even in the mandible. Nerve bloc is not preferable, just in special cases. Local infiltration is less painful when done correctlyPage  7
    • Handicapped Patient Several issues arise concerning the use of local anesthesia with this population. One of these is lip biting – Consideration should be given to choosing a short-acting local anesthetic to reduce the possibilityof post-operative trauma from lip biting. – Another choice would be to avoid mandibular blocks and utilize infiltration, periodontal ligament A second issue with local anesthesia is the inability to determine from a non-communicative patient when an acceptable level of anesthesia has been obtained. – When in doubt second injections and alternative routes (e.g., buccal, mylohyoid, intraligamentary)Page  8
    • Handicapped Patient An unresolved issue in treating these patients is that severely retarded patients have a higher pain threshold than the general population. Some clinicians therfore choose not to use local anesthetic when the procedures involve minor restorative needs (e.g.,body pits or minor occlusal decay). These patients are difficult to control. Injecting such a patient can be extremely difficult and may pose a significant danger to the patient and the staff. One must choose a shorter needle and/or a larger gauge needle which is less likely to be bent or broken. However it is better to use general anesthesia with Handicapped patients.Page  9
    • Patients receiving anticoagulation or suffering frombleeding disorders oral procedures must be done at the beginning of the day because this allows more time to deal with immediate re-bleeding problems. Also the procedures must be performed early in the week, allowing delayed re-bleeding episodes, usually occurring after 24-48 h, to be dealt with during the working weekdays. Local anesthetic containing a vasoconstrictor should be administered by infiltration or by intraligamentary injection wherever practical. Regional nerve blocks should be avoided when possible. Local vasoconstriction may be encouraged by infiltrating a small amount of local anesthetic containing adrenaline (epinephrine) close to the site of surgery.Page  10
    • Pregnant woman Local anesthesia are not teratogenic, and may administered to pregnancy patient is usual clinical doses. Large dose of prilocaine are know to cause methemoglobinemia which could cause maternal & fetal hypoxia. Local vasoconstriction – Delay uptake from the site of injection – Increase the effectiveness & duration There is no specific contraindication to these vasoconstrictors in a pregnant patient although it is prudent to use minimal effective dose.Page  11
    • Pregnant woman• Lidocaine + vasoconstrictor: most common local anesthetic used in dentistry extensively used in pregnancy with no proven ill effects, Esters are better to be used.• accidental intravascular injections of lidocaine pass through the placenta but the concentrations are too low to harm fetus• Drug classes: B: lidocaine, prilocaine, etidocaine C: mepivacaine, bupivacaine Not yet assigned: Procaine• The need for careful Hx taking & for aspiration & slow injected technique is obviousPage  12
    • For Information : Pregnancy drug Clases Medications are grouped into 1 of 5 categories based on the potential for producing birth defects. The categories are A, B, C, D and X. Generally speaking, drugs that fall into either class A or B are considered safe and are routinely used. There may be exceptions. Category A: Controlled studies in pregnant women fail to demonstrate a risk to the fetus in the first trimester with no evidence of risk in later trimesters. The possibility of harm appears remote. Category B: Presumed safety based on animal studies, with no controlled studies in pregnant women, or animal studies have shown an adverse effect that was not confirmed in controlled studies in women in the first trimester and there is no evidence of a risk in later trimesters. Category C: Studies in women and animals are not available or studies in animals have revealed adverse effects on the fetus and there are no controlled studies in women. Drugs should be given only if the potential benefits justify the potential risk to the fetus. Category D: There is positive evidence of human fetal risk (unsafe), however in some cases such as a life-threatening illness the potential risk may be justified if there are no other alternatives. Category X: Highly unsafe: risk of use outweighs any potential benefit. Drugs in this category are contraindicated in women who are or may become pregnant.Page  13
    • GERIATRIC PATIENT When choosing an anesthetic, we are largely concerned with the effect of the anesthetic agent upon the patients cardiovascular and respiratory systems. increased tissue sensitivity to drugs acting on the CNS Decreased hepatic size and blood flow may reduce hepatic metabolism of drugs hypertension is common and can reduce renal function Same prevention procedures used with childrenPage  14
    • LIVER DISORDERS Advanced liver diseases include: Liver cirrhosis - Jaundice Potential complications: 1. Impaired drug detoxication e.g. sedative, analgesics, general anesthesia. 2. Bleeding disorders ( decrease clotting factors, excess fibrinolysis, impaired vitamin K absorption). 3. Transmission of viral hepatitis.ManagementAvoid LA metabolized in liver: Amides (Lidocaine, Mepicaine), esters should be usedPage  15
    • Drug-Drug Interaction Local anesthetics and vasoconstrictor may interact with other prescribed drugs. list of administrated drugs to the patient can play a role in the local anesthetic choice.Page  16
    • Sedation : Who Autism or Other Special Needs Our sedation dentistry practices are a solution for patients with physical or mental challenges, and for individuals emotionally uncomfortable in the traditional dental office setting. Dental anesthesia services can provide a way to accomplish complete dental care in a more pleasant experience. Cancer Patients dealing with cancer have enough to worry about without the added stress of dental care. Treatments such as radiation and chemotherapy often call for dental care that not all dentists are willing or qualified to perform. When you need a dentist who understands the complexities of cancer treatment, you can turn to Dr. Lee Lichtenstein and staff.Page  17
    • Sedation : Who Fear and Anxiety Sedation dentistry is a great alternative for those who suffer from fear, anxiety and phobias stemming from dental appointments. With sedation dentistry, modern, safe sedation techniques allow the fearful patient to have dental procedures done without the anxiety. Low Pain Threshold Many people perceive pain differently than others, or at a much smaller stimulus. these patients will have their own personal perception of pain altered and will be virtually pain free during the dental treatment.Page  18
    • Sedation : Who Active Gag Reflexes Some patients will gag before the smallest X-ray film is even placed in their mouth, or before they have a simple impression taken. Using sedation, services even for the simplest dental procedures can eliminate the problems caused by gagging. Extensive Treatment Sedation dentistry is great for sophisticated procedures such as implant dentistry, or full mouth rehabilitation. Patients having extended procedures such as periodontal surgery and root canal therapy are more comfortable when these dental procedures are done with our anesthesia services.Page  19
    • General Anesthesia for special Patients General anaesthesia is a procedure which is never without risk (including the risk of death). In assessing the needs of an individual patient, due regard should be given to all aspects of behavioural management and anxiety control before deciding to treat or refer for treatment under general anaesthesia. General anaesthesia for dental treatment should only be administered in a hospital setting with critical care facilitiesPage  20
    • Disadvantage of GA Apart from the risk of serious complications (which, while very small, is still significantly higher than for conscious IV sedation), general anesthesia has a few major disadvantages: (1) Complications are more likely with GA compared with conscious sedation both during and after the procedure. (2) Its not recommended for routine dental work like fillings. little bits of tooth, other debris or saliva could enter the airway and produce airway obstruction or cause illnesses like pneumonia. (3) Laboratory tests, chest x-rays and ECG are often required before having GA, because of the greater risks involved.Page  21
    • Disadvantage of GA (4) Very advanced training and an anesthesia team are required, and special equipment and facilities are needed. GA introduces a number of technical problems for the operator (i. e. dentist), especially when a "breathing tube" is involved: the tongue is brought forward more into the dentists way by the airway tubing, the muscles are paralysed so the operator is working against a dead weight all the time. (5) Patient cant drink or eat for 6 hours before the procedure (otherwise, vomiting is possible and this would be extremely dangerous during GA). (6) Its expensive. (7) GA does nothing to reduce dental anxiety. The next time the pateint need any work, or even a routine check-up, youll most likely be as afraid as ever.Page  22
