  • a) Nasal cannulas should only be used in patients who breathe adequately through their nostril .It is for obligatory nasal breather ie: newborn & for adult who req minimal O2 enrichment.b). Use of cannulae is not indicated in patients who have severe hypoxia, poor respiratory effort, blocked nasal passages, apnea, or are mouth breathers.c) comfortable,can eat n drinks, cheap, well toleratedd) Pressure sore, dry nasal mucosa, epistaxis, can only deliver low concentrations of oxygen (It can deliver from 24% to 40% oxygen at a flow rate of 0.26-1.58 gal (1-6 L) per minute)
  • Oropharyngeal airway/ guedel airway.To protect airway (airway adjunct) by preventing the tongue fall backwards to obstruct the hypopharynx in unconscious pt.Do not use in conscious pt who hv intact gag reflex that can cause vomiting and aspiration.Wash hand, put on glove – choose correct size (tragus of ear to angle of mouth) – open mouth by chin lift manouver – insert it in reverse position – as it advanced to back of mouth, rotate it.
  • Nasopharyngeal airwayFor pt with gag reflex and lower facial traumaNasal obstruction n base skull # is suspectedWash hand and put on glove – choose correct size (lumen size = size of pt finger) – lubricate the tip with KY gel – insert the tip into nostril downward – until flange rest on nostril – ventilate with bag and mask device
  • CombitubeUsed in pt with difficult airways secondary to severe facial burns, trauma, upper airway bleeding and vomiting where there was an inability to visualize the vocal cords.The Combitube is a twin lumen device designed for use in emergency situations and difficult airways. It can be inserted without the need for visualization into the oropharynx, and usually enters the esophagus. It has a low volume inflatable distal cuff and a much larger proximal cuff designed to occlude the oro- and nasopharynx (1-4). If the tube has entered the trachea, ventilation is achieved through the distal lumen as with a standard ETT. More commonly the device enters the esophagus and ventilation is achieved through multiple proximal apertures situated above the distal cuff. In the latter case the proximal and distal cuffs have to be inflated to prevent air from escaping through the esophagus or back out of the oro- and nasopharynx.increased incidence of sore throat, dysphagia and upper airway hematoma,esophageal ruptureKnown esophageal disease
  • Sims speculumUse: 1)To visualize vaginaesp in gynae cases. Useful for visualising fistula (abnormal holes or connections) and prolapse (protrusion) of the rectum or bladderinto the vagina. In sims position, abdominal viscera fall away from back and pelvis and allowing full inspection of vagina) – 2)High Vaginal Swab for C&S 3)Pap smear 4)D&CSims position:A position where a patient is on the left side with the right knee flexed against the abdomen and the left knee slightly flexed.Not self-retaining,therefore require assistant.
  • a) Secondary arrest labour (cessation of cervical dilatation after initial normal active phase) b) Cephalo-pelvic disproportionc) If amniotic membrane not ruptured yet, rupture it artificially. Then give I.V oxytocin to manipulate the ‘power’ to increase uterine activity and promote cervical dilatation (Augmentation of labour). Hydration is important also.However, most pt in secondary arrest will end up with CS.d)Epidural analgesia: bcoz augmentation with oxytocin is > painful compared to spontaneous contraction.
  • Progesterone-only long acting reversiblehormonal contraceptivebirth control drug (depo-medroxyprogesterone acetate, injected every 3 months)Primary action: inhibit follicular development and prevent ovulation. Secondary action:of all progestogen-containing contraceptives is inhibition of sperm penetration by changes in the cervical mucus (thicker) Other: prevent implantation (causes the endometrium to become thin and atrophic)c) Very effective (PI<1)Good compliance once injectedInfrequent visit to doctorCan be use during lactationNo estrogen. No increased risk of deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, or myocardial infarction.Decreased risk of endometrial cancer.d) Nausea, weight gain, headache, breast tenderness, acne,moodinessOccasional breakthrough bleedingAmenorrheaDelay in return of fertility of up to 4 months once stoppedOffers no protection against Sexually transmitted diseases (STDs). e) Pearl index<1

  • a)130 bpmb) About 10 bpmc) Type 2 decelerationd) Fetal distress due to: cord round neck,meconeum aspiration, cord prolapse etcNOTES:Baseline fetal heart rate (FHR) is the mean level of the FHR when this is stable, excluding accelerations and decelerations. It is determined over a time period of 5-10 minutes, expressed as beats per minute (bpm)1. Preterm fetuses tend to have values towards the upper end of the normal range.Baseline variability is the minor fluctuation in baseline FHR. It is assessed by estimating the difference in bpm between the highest peak and lowest trough of fluctuation in one minute segments of the trace1.Accelerations are transient increases in FHR of 15bpm or more above the baseline and lasting 15 seconds. Accelerations in preterm fetuses may be of lesser amplitude and shorter duration1.Decelerations are transient episodes of decrease of FHR below the baseline of more than 15 bpm lasting at least 15 seconds, which are:Early – uniform, repetitive decrease of FHR with slow onset early in the contraction and slow return to baseline by the end of the contraction1Variable – repetitive or intermittent decreasing of FHR with rapid onset and recovery. Time relationships with contraction cycle may be variable but most commonly occur simultaneously with contractions1.Complicated variable decelerations - the following additional features indicate the likelihood of fetal hypoxia:Rising baseline rate or fetal tachycardiaReducing baseline variability Slow return to baseline FHR after the end of the contractionLarge amplitude (by 60bpm or to 60bpm) and /or long duration (60 seconds)Loss of pre and post deceleration shouldering (abrupt brief increases in FHR baseline).Presence of post deceleration smooth overshoots (temporary increase in FHR above baseline)1Prolonged decelerations - decrease of FHR below the baseline of more than 15 bpm for longer than 90 seconds but less than 5 minutes1.Late decelerations - uniform, repetitive decreasing of FHR with, usually, slow onset mid to end of the contraction and nadir more than 20 seconds after the peak of the contraction and ending after the contraction1. 3. Classification of CTGs3.1 Normal antenatal CTG trace: The normal antenatal CTG is associated with a low probability of fetal compromise and has the following features:Baseline fetal heart rate (FHR) is between 110-160 bpmVariability of FHR is between 5-25 bpmDecelerations are absent or earlyAccelerations x2 within 20 minutes.3.2 Normal intrapartum CTG trace:The normal intrapartum CTG is associated with a low probability of fetal compromise and has the following features:Baseline FHR is between 110-160 bpmVariability of FHR is between 5-25 bpmDecelerations are absent or early The significance of the presence or absence of accelerations is unclear. Therefore, exclude accelerations during interpretation.3.3 Non-reassuring CTG trace is where one of the following features is present:The following features are unlikely to be associated with significant fetal compromise when occurring in isolation. The presence of two or more features is considered abnormal as these may be associated with fetal compromise and require further action (see 3.4).Baseline FHR is between 100-109 bpm or between 161-170 bpmVariability of FHR is reduced (3-5 bpm for >40 minutes)Decelerations are variable without complicating featuresDo not consider the absence of accelerations in intrapartum interpretation as abnormal.3.4 Abnormal CTG trace is where:The following features are very likely to be associated with significant fetal compromise and require further action:Two of the features described in non-reassuring CTG trace are present, ORBaseline FHR is <100 bpm or >170 bpmVariability is absent or <3 bpmVariability is sinusoidalDecelerations are prolonged for >3 minutes / late / have complicated variables

  • Fasciotomyb) Swelling of the muscle – usually as a result of post-traumatic bleeding and oedema.o   Initially only venous flow is disturbed, and arterial flow (due to its greater pressure) still occurs.o   Eventually, the pressure within the compartment exceeds the arterial pressure, and the muscle begins to undergo ischaemia. § The main arteries in the compartment have a higher pressure than the arterioles, and thus these may not be occluded until late on, if at all§ Other structures close by are also affected by the ischaemia – e.g. nerves, but the nerves are not affected until the pressure is very high!§ This means that distal pulses and neurological exam are usually normal until VERY LATE ON! ·         If there are reduced or absent pulses, then it is likely the diagnosis is too late to stop severe ischaemic damage. c) Permanent nerve damageInfectionLoss of limbDeathCosmetic deformity from fasciotomy

Benefit of cmr, it will reduce the pain, reduce deformity, reduce dysfunction.***must check either ptnt understand or not and if they have any question. Then sign the consent form.
  • Pathophysiology1) Urate crystal deposited in minute clumps in the connective t/s and articular cartilage (commonest sites are the small joints of the hands and feet)2) They can remain inert for month or years.3) Possibly as a result of local trauma, the crystal can disperse into the joints and surrounding t/s which excite inflammatory rxn.4) Clumps or tophi vary in size. It may destroy cartilage and periarticular bone and penetrate the skinCommon sitesType of t/s:- Joints- Periarticular t/s- Tendons- BursaeSites:- Metatarsophalengeal joints of big toe (adasorang pt harituada swelling and discharge at both feet)- Finger joints- Ankle- Achilles tendon- Olecranonbursae- Pinnae of earsSequlae1) Cartilage degeneration.2) Renal dysfunction.3) Uric acid kidney stone.
  • In very young children à bone ends are largely cartilaginous & therefore do not show in x-ray è Fracture at these sites are difficult to diagnoseChildren bone less brittle à more liable to plastic deformity compare to adult. Incomplete fractures – torus fracture (buckling of the cortex)& greenstick fractures are common in children compare to adultPeriosteum is thicker than in adult bones; this may explain why fracture displacement is more controlledCellular activity of periosteum is more active, which is why children’s fracture heal more rapidly than adult (the younger the quicker rate of union)Non-union is very unusualBone growth involves modeling & remodeling à fracture deformity can be reshape to normal over time (except rotational deformity)Damage to growth plate can have serious effect compare to adult

    63. 63. Short case..• c/o: 40 years old Malay lady presented with painful swelling of right ring finger. please examine her. 1) Position the most important for hand examination is to position both hands correctly. put the hands on top of a pillow with the patient in sitting position. ask the patient to abduct the fingers as maximum as she can because from this position, we can already detect any neurological disorder related to the hands, specifically motor disorder.
    64. 64. • 2) Inspection (look) inspection is divided into 2, towards the pathology (mass) itself, as well as towards the hand as a whole. 1st, compare both hands, dont take too much time doing this, just inspect surfacely because the examiner can be annoyed if korang sibuk2 nak pegang2 ke, angkat2 ke, or give excessive attention to the normal hand. then, check for any signs of wasting or skin discoloration, or any obvious changes related to the hand. for the mass or swelling, inspect it just like you inspect any lump and bump in surgery. do not forget to include the edge, border, size, site, character of the mass (fungating, etc), surface, and any discharge noted. for the site, describe precisely where is the origin of the mass. dont forget to check fo any associated deformity, such as nail deformity or finger deformity.
    65. 65. • 3) Palpation (feel) begin with soft palpation, in order to detect any tenderness associated with the mass, xkesahlah at the mass itself or the area surrounding the mass. then, dont forget to check for circulatory status, i.e. CRT and pulse, as well as the sensation whether it is intact or not.
    66. 66. • 4) Movement (move) for movement, just test for active movement first and examine the ROM. assess the ROM of all fingers of the hand, not just the affected finger, because others can be affected too. for example, ring finger share the same tendon with the little finger, so, if one is affected, the other might be affected too.
    67. 67. • 5) Ending complete your examination by checking the lymph node, other features of malignancy, or any relevant examination related to your differentials.
