  13. 13.  The serum refers to plasma from which the clotting proteins have been removed. Most of the proteins remaining are albumin and Ig. (Serum = Plasma – Clotting factors) Normal Blood pH is a within the narrow range of 7.35 to 7.45, making it slightly alkaline.
  14. 14.  By volume, the red blood corpuscles constitute about 45% of whole blood It is a circular, biconcave cell without a nucleus Diameter about 7.5μm Thickness at the periphery is about 2 μm and at the centre it is 1 μm 95% of the dry weight of the RBC is due to Hb. Hb is interwoven in the stroma of RBC so if a RBC is cut, the Hb is not extruted Normal range 4.7 to 6.1 million/cmm(male), 4.2 to 5.4 million/cmm (female) Normal survival time is 120 days
  15. 15.  By volume the WBC constitute about 0.7% of whole blood Normal range 4000-11000 /cmm of blood On the staining property by one of the Romanowski’s stain (Leishman’sstain) they devided in to two types Granulocytes Non granulocytes Neutrophil (60-70%) Lymphocytes (25-30%) Eosinophil (1-4%) Monocytes (2-8%) Basophil (0.2-1%)
  16. 16.  Diameter 10-12 μm Mature neutrophil have several lobes 2,3 up to 7 Cytoplasmic granules are amphophilic, take both acidic and basic stains Granules are two types Primary/Azurophilic/Lysosomal Secondary/Specific Proteolytic & Amylolytic granules Lactoferrin MPO enzymes granules Alkaline phosphates Lysosomal enzymes granules Vit.B12 binding proteins
  17. 17.  Diameter 10-15 μm Usually bilobed Cytoplasmic granules are very coarse and contain alkaline materials Eosinophilic peroxidase enzymes Major basic protines (50%) Eosinophilic cationic protines
  18. 18.  Diameter 8-10 μm Nucleus is irregular and often ‘S’ shaped Cytoplasmic granules are coarse and contain Histamine Heparin Acid peptides Acid hydrolases Neutral proteolytic enzymes
  19. 19.  They are devided in to following types Size Cell typeSmall Large (10%) T-cells B-cells 8-10 μm 10-12 μm( wholly consist ( cytoplasm abundant ) of nucleus,cytoplasm occupying a narrow rim round the nucleus)
  20. 20.  Largest cell of WBC Diameter 12-20 μm Nucleus are horse shoe shaped appearance
  21. 21.  Normal counts are about 1.5-4 lacs/cmm Diameter between 2-4 μm In the circulating blood they are in inactive state and have a disc like structure When there is injury they become activate and spherical in structure Critical count- if the count is below 40,000/cmm then haemorrhagic manifestations started
  22. 22. Blood performs many important functions within the body including:- Supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells) Supply of nutrients such as glucose, amino acids and fatty acids (dissolved in the blood or bound to plasma proteins (e.g., blood lipids)) Removal of waste such as carbon dioxide, urea, and lactic acid Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies Coagulation, which is one part of the bodys self-repair mechanism (blood clotting after an open wound in order to stop bleeding) Messenger functions, including the transport of hormones and the signaling of tissue damage Regulation of body pH Regulation of core body temperature

  28. 28.  Leukemiais a Clonal malignant neoplasm of the hematopoietic stem cells characterized by the proliferation of abnormal (leukemia)blast cells and impaired production of normal blood cells. Itis classified on the basis of the cell type involved and the state of maturity of the leukemic cells in to 2 types Acute Chronic (+ of immature cells) (well differentiated cells) AML ALL CML CLL
  29. 29. Immunologic % of Cases FAB Subtype CytogeneticSubtype Abnormalities Pre-B cell ALL 75 L1,L2 t(9;22), t(4;11), t(1;19) T- cell ALL 20 L1,L2 14q11 or 7q34 B- cell ALL 5 L3 t(8;14), t(8;22), t(2;8)
  30. 30.  Acute lymphoid leukemias (ALLs) are predominantly cancers of children and young adults . Peak incidence approximately four years age. More frequent in boys than in girls. Exposure to high-energy radiation in early childhood increases the risk of developing T cell ALL. The cells are heterogeneous in size, have round or convoluted nuclei, high nuclear/cytoplasmic ratio, and absence of cytoplasmic granules.
  31. 31.  The leucocyte count may vary from 1000/cmm to 5 lacs/cmm. The appearance of blast cells in blood film is usually diagnostic. Diagnosis of ALL is confirmed by demonstration of 20% lymphoblasts in the bone marrow. There is associated anaemia and thrombocytopenia. The coagulopathies are usually mediated by thrombin activation rather than primary fibrinolysis and may lead to both hemorrhagic and thrombotic complications.
  32. 32.  Pulmonary complications secondary to lymphoblastic leukemia are pneumonia, pulmonary leukostasis, malignant pleural effusion and / or pulmonary infiltration and upper airway obstruction. The cause of upper airway obstruction can be epiglottitis, enlarged lymph nodes, laryngeal mass comprised of leukemic cells. In a lymphoid malignancy presence or combination of nasopharyngeal obstruction, laryngeal displacement, malignant infiltration of tonsils and pharynx and potential tracheal compression put such a patient at extreme risk for airway complications.
  33. 33.  Decreased resistance to infection Hyperviscosity syndrome— drowsiness, coma, focal neurological defects CNS involvement Anemia thrombocytopenia bleeding tendency DIC
  34. 34. Parameters Good poor WBC low High(>50x10 9 /l) Gender Girls Boys Age Child Adult or infant. Immunophenotype C-ALL B-ALL Cytogenetic Normal, Ph+,11q23 hyperdiploid rearrangements
  35. 35. 1. General Management-: The increased white cell mass may be reduced by leukophoresis. Frequent blood transfusions to maintain Hb levels at >7 g/dL. Platelet transfusions are required if counts remain <10 to 20,000 or if <50,000 and remaining symptomatic or undergoing an invasive procedure. Give FFP and other blood products as needed. Neutropenia management, including protective isolation, appropriate antibiotic therapy, ± granulocyte- colony stimulating factor. GVHD is managed by supportive treatment and parenteral nutrition. PGE1 and immunosuppression may be helpful. Psychological support for both patient and family is vital.
  36. 36. 2. Medical therapy-: Therapy consists of a three-phase treatment induction, CNS prophylaxis, and maintenance Induction therapy with prednisone, vincristine, L- aspara-ginase, and daunorubicin Maintenance therapy with 6- mercaptopurine, methotrexate, cyclophosphamid e, and prednisone is given in a cyclical fashion for 2 or more years.
  37. 37. Complications arising from the therapy- Tumor lysis syndrome—Hyperkalemia, hyperuricemia, and acute renal failure may follow rapid destruction of a large white cell mass. Neutropenia and immune compromise with an increased risk of infection Anemia Thrombocytopenia leading to spontaneous bleeding, usually from intravascular catheter sites, skin, lung, gut, and brain Lung fibrosis (e.g., after radiotherapy, bleomycin) Myocardial failure (e.g., after mitoxantrone) Graft versus host disease (GVHD)—Features include mucositis, hepatitis, jaundice, diarrhoea, abdominal pain, rash, and pneumonitis
  38. 38.  Airway obstruction is the primary mechanical emergency of the respiratory system in patients with malignancy. Obstruction can occur at the level of larynx, trachea or bronchi. Symptomatic relief is the main objective for patients with airway obstruction. Patient should be allowed to assume position of maximum comfort. If pt. unable to maintaine spontaneous respiration then intubation done.
  39. 39.  On operation table, monitoring for heart rate, ECG, non - invasive blood pressure(NIBP) and pulse oximetry Is instituted. In these pt. orotracheal intubation is defficult b/c of restricted mouth opening , edema arround mouth, lips and pharynx. Fibreoptic scope guided tracheal intubation is the technique of choice in an anticipated difficult airway. In these pt. mucosa is edematous and hemorrhagic. So, the use of local anaesthetic agents for awake fibreoptic intubation carried a potential risk of toxicity due to direct absorption of local anaesthetic drugs into the systemic circulation.
  40. 40.  Induction of anaesthesia with intravenous agents carries an inherent risk of aponea and subsequent failure to ventilate. Use of neuromuscular blocking drugs is avoided to prevent cannot ventilate cannot intubate (CVCI) situations. Tracheal intubation under inhalational anesthesia is a good option when fibrescope is not available. Pt. is premedicated with inj.Glycopyrolate & inj.Midazolam. preoxygenation with 100% oxygen done for five minutes
  41. 41.  Inhalation anaesthetic agents is mixed with oxygen. Direct laryngoscopy and intubation should be done gently to avoid trauma to oro pharyngeal tissues and subsequent bleeding. Tracheal tube should be well lubricated for a smooth passage. In most cases, the proper tube size is 0.5 to 1.0 mm ID smaller than predicted for age because of airway inflammation and edema Proper placement of tracheal tube is confirmed by end tidal carbon dioxide (EtCO2) and chest auscultation.
  42. 42.  100% oxygen is given after inhalation agents is switched off Patient remained hemodynamically stable throughout the procedure. After become conscious and tolerating the tracheal tube then shifted Laryngeal mask airway (LMA) has been recommended in difficult airway but in these patient it is not useful because it does not prevent the risk of compression of airway in the neck and it’s placement is difficult and dislodgment common due to edematous and swollen oral structures.
  43. 43.  Intubating laryngeal mask airway is a good option but the risk of bleeding is more during its placement. Nasotracheal intubation and tracheostomy are contraindicated due to deranged coagulation profile. Oral airway insertion is avoided to prevent bleeding from fragile mucosa. Steroids has been used successfully as an adjunct in oropharyngeal obstruction in patients with leukemia.
  44. 44.  The influence of corticosteroids on airway patency in patients with pharyngeal swelling may involve some direct vascular effects in addition to well-established anti-inflammatory effects (stabilization of vascular endothelium and lysozymal membrane permeability and suppression of phagocytosis). The direct vascular effects include increased sensitivity of the vascular network to endogenous vasoconstrictors and a competitive blockade of estradiol receptors on the vascular network.
