Introduction: The treatment of COVID-19 is still challenge. So convalescent plasma can be an important alternative of treatment. Protocols with nursing care during infusion is very important to guide an effective and safety care., Objective: to analyze the evidence in the literature on the action of convalescent plasma, of the use of protocols with nursing care to use convalescent plasma and build a nursing care protocol for transfusion in patients with COVID-19., Methods: Methodological study carried out in two stages: scoping review. The search was done using the descriptors: convalescent plasma transfusion, convalescent plasma, and acute respiratory syndromes or COVID-19, to found protocols and effectiveness of convalescent plasm. Beside was done a specialist panel to build the protocol., Results: Low-evidence studies have shown improvement in the clinical signs of COVID-19 using Convalescent Plasma, reduction or elimination of viral load, benefits in the production of lymphocytes, decreases C-reactive protein, increases titers of anti-SARS-CoV-2 antibodies, positive evolution in lung involvement identified by X-rays, decrease in hospitalization. No studies were found in the databases on the protocol for clinical nursing care in plasma transfusion. Therefore, a protocol was developed with the description of clinical nursing care to be performed before, during and after the transfusion by plasma: checking of vital signs and indicative signs of transfusion reaction, measurement of oxygen saturation, assessment of venous access and checking of the level of consciousness., Conclusion: There are no evidence studies to support the use of plasma, nor anything related to bundles., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Author(s).)

The author makes an attempt to prove the following facts on the basis of his histological studies: 1. The mechanical process of cutting out small bone fragments from the outer cortex of the long bones of fragments from the outer cortex of the long bones of living humans results in an immediate devitalisation or emptying of the lacunae. 2. In almost 74% of the cases, there is an emptying of the lacunae or absence of the mature osteocytes, as well as degeneration--albeit to a varying degree--in almost 95% of the remaining osteocytes. 3. These facts, i.e. immediate devitalisation of these small fragments of living bones, prompted the author to question the expression "bone graft", even with free or floating bone fragments taken from the same patient, i.e. also with the socalled autogenic or autologus bone grafts. 4. Transplanting or grafting a living bone fragment from the donor area to a recipient area will stimulate the recipient area to form new bones. In this manner, it is possible to achieve osteogenetic induction, and expression which respresents the course of facts with biological accuracy. 5. The mature osteocyte does not participate as a living cell in the osteogenetic process of rehabilitation, does not multiply, and dies. 6. The new bone is shaped by the recipient and not by the grafted bone of the donor.
