A fracture when one side of the fractured bone has broken and the other side is bent is called a greenstick fracture. Because of this condition, it is called an incomplete break. This is also known as growth plate injury. Children's bones are still in a developing stage and are more susceptible to greenstick fracture because their bones are more pliable than adults'. This can be compared to the breaking of a fresh branch of a tree. The inner side remains intact even though it is bent while it snaps on one side. It wont result in a complete disruption of the bone's cortex but there will be a bowing at the fractured area.
To bring back the bone into proper position, it has to be bent back and this procedure is called reduction.
A cast for about six weeks will help regain the position. Since greenstick fractures mostly occur in the middle and slower growing parts of the bone, it takes longer time to heal. In a growth plate injury, careful treatment and accurate reduction are necessary for the bone to continue to grow normally. In some cases, plastic deformation of the bone also may occur. This is a condition in which the bone permanently bends but does not break. For such injuries, an osteotomy or bone cut may be necessary to realign the bone if the fracture is a fixed one.
Normally when children fall with outstretched arms, they suffer injuries or broken bones in their hand, wrist, arm and elbow. The orthopedist will request an X-ray of the injured parts. He will also conduct some tests to ensure that blood circulation and nerves in the affected portions are not affected due to the injury. Some symptoms include acute pain, tenderness, swelling, inability to rotate or turn the forearm and any type of deformity about the elbow, forearm or the wrist. Depending on the type of fracture and the degree of displacement, the doctor will decide about the treatment. A surgery is required only if the bones break through the skin and the physician will be able to bring back proper alignment of the bones through manipulation.
Dyspnea is commonly known as breathing difficulty or shortness of breath. It is noticed as difficulty in breathing or labored breathing. Tachypnea refers to rapid breathing. Progressively it can lead to hyperventilation such as experienced during an anxiety attack. Studies indicate that the origin of dyspnea is initiated with inaccurate central nervous system to the lungs with respect to breathing.
The etiology of dyspnea is related to conditions such as Pulmonary Embolism (PE), asthma, COPD, pulmonary ischemia and pneumonia. The management of dyspnea is only effective when the underlying causes are treated. In case of trauma, pneumothorax is an acute trigger for initiating the onset of dyspnea and hence emergency care is given to prevent internal bleeding that is caused in the pneumothorax. This condition can also progress into tachypnea and varied lung and heart sounds which has to be managed with effective ER procedures.
Positional dyspnea: If a person suffers dyspnea when lying down, it might be suggestive of CHF or pericardial effusion.
Exertional dyspnea: This occurs when there is reduction in oxygen supply and is mostly noticed in patients suffering cardiac disease or anemia.
Transient dyspnea: This situation usually resolves without medical intervention and is triggered by reversible causes such as panic attacks.
Recurrent dyspnea: Here the patient suffers these episodes many times.
Conditions such as pulmonary embolism can also lead to dyspnea along with tachycardia and diminished breathing patterns. Dyspnea is an immediate progressive condition usually associated with previous history of trauma or illness such as Tuberculosis, bronchopneumonia, infectious mononucleosis and sepsis in certain scenarios. Since dyspnea is an associated condition and it is predominantly an upper airway obstruction, the treatment measures are often related to avoiding exposure to chemicals, pollen, toxic fumes and gases such as carbon monoxide. Diagnostic tools such as Pulse Oximetry, blood tests for anemia, ECG and metabolic study are used to aid the diagnosis and then initiate appropriate treatment.
Blood transfusion is one of the important procedures administered in healthcare centers to meet surgical and trauma needs. This procedure is categorized under transfusion medicine section. Blood transfusion is a high-risk procedure as it involves multiple protocols and guidelines for safe and effective transfusion.
Guidelines and Procedure
Transfusion medicine has high significance as it involves the transfusion of blood and blood products depending upon the patient needs. Blood required for the transfusion is obtained from blood banks, which are established either by the government or privately following NCCLS standards for the blood banks. The standards are evaluated by organizations such as WHO to set a uniform and global protocol for safe transfusion. Blood transfusion is predominantly done to increase the percentage of hemoglobin in anemic patients and also to replace vital components such as platelets and serum proteins in some medical conditions. Other reasons for blood transfusion is to replace the amount of blood lost during surgery or trauma. Patients suffering thrombocytopenia (any disorder in which there is an abnormally low amount of platelets) might be in need of platelet transfusion.
Blood banks are authorized by the government to collect blood of different groups. Some of the rare groups include B negative, O negative and Bombay blood group. In these situations, the names and the address of these respective rare blood types are noted to ensure timely availability in case of a transfusion request. Cancer patients also require transfusion in case of conditions such as leukemia and malignant carcinomas associated with spleen or bone marrow. Leukocyte reduction procedure is followed in some transfusion centers in order to minimize the incidence of transfusion-associated allergic reactions. All donors are checked for a three-month gap before the subsequent transfusion to facilitate fresh blood collection from the donors containing viable red blood cells.
Different types of Blood transfusions:
Fresh Whole Blood: This is mostly needed during cardiac surgery or massive hemorrhage. Fresh Whole blood has RBC, plasma and fresh platelets.
Packed RBC: This is mostly needed to raise the hematocrit (the proportion of total blood volume that is composed of red blood cells).
Frozen packed RBC: Stored for nearly 3 years, frozen packed RBC is sparingly used. It is often used for rare blood groups. Patients suffering severe leukoagglutinin reactions or anaphylactic reactions might need this.
Leukocyte-Poor Blood: Patients who suffer severe leukoagglutinin reactions might need this. It is an expensive process as WBC are removed by centrifugation.
Precautions and risks
Transfusion is a very important procedure and hence primary analysis of the donor blood is done in order to avoid blood borne sepsis, transfusion allergies and organ damage. The donor blood is always cross-matched with the recipient's in order to check the compatibility of the blood. All procedures are documented to ensure safety and tracking of a transfusion procedure, as it is associated with medico-legal protocols. The A and B antigens are the first check before transfusion. In emergencies, type O/Rh-negative blood can be given to any recipient and usually packed cells are given. The Rh factor has also to be tested. Blood from the donor is also investigated for infections such as HIV 1&2, HBV, HCV, and VDRL to ensure safe transfusion.
Blood is collected from the healthy donor in a blood bank by administering venipuncture procedure from the brachial region. The obtained blood is transported for immediate need in surgeries or stored for few days in case of a scheduled surgery having the requirement for the particular blood group. The transfusion requirement is clearly stated in the surgical form and the blood bank technicians provide number of units required on the given date. Some of the common side effects associated with blood transfusions are infections of both viral and bacterial origin obtained from an infected donor. Receipt of blood contaminated with gram-negative bacteria often causes septic shock, Disseminated intravascular coagulation or DIA (a large amount of procoagulant enters the blood stream over a short period of time, overwhelming the body’s ability to replenish coagulation factors and causing bleeding) and acute kidney injury. Receipt of blood with gram-positive bacteria causes fever and Bacteremia (presence of bacteria in blood) but rarely causes sepsis.
