The ancillary equipment is a generic term that refers to all of the hip replacement surgery instruments in orthopaedics. Each instrument set is typically packed in 2 or 3 boxes, and each surgeon has a limited number of instrument sets at his disposal per operating day. Single-use reamers are devices that are used on a single patient and then discarded. Within a classic ancillary, it seems that it would be judicious to compare the medical-economic differences between the use of single-use reamers versus reusable reamers.

Also intraoperative mechanical ventilation may cause volutrauma, barotrauma, or atelectrauma as a result of lateral position during hip replacement surgery. pulse pressure variation index (PPV) is a dynamic parameter that is related to amplitude changes observed in pulse oximetry results, and it is related to amplitude variations that are measured in pulse oximetry results. 132 oximetry variations are shown as pulse pressure variation index (P) The dynamic variable is identified as pulse pressure variation index, which is correlated with amplitude changes observed in pulse oximetry measurements. Patients' outcomes have been promising with goal directed fluid therapy, which has shown positive results on patient health. In a research where PVI changes were guiding fluid therapy, the researchers found good results. In addition, goal directed fluid therapy, including PVI and CVP, was used by the investigators to track static and dynamic hemodynamic variables during hip replacement surgery, and fluids are applied according to our fluid therapy protocols. In this report, the investigators in both groups will use fluid according to PVI results, so if any difference is found between the two groups will be due to the differences in respiratory parameters between the two groups. The changes in etCO2 are due to the blood flow variations and is closely related to cardiac output changes, as CO2 synthets and formed in lungs are constant, and it is linked to lung changes. It is known that when CO2 is present in the tissues and lungs remain constant. The decrease in PETCO2, a result of cardiac output decrease, cannot be explained only by the reduction of cardiac output decrease, but it can also be explained by changes in CO2 production caused by changes due to oxygen supply dependence. On the other hand, when cardiac output is high, pulmonary blood circulation is no longer a limiting factor for PETCO2 formation, and PETCO2 is attributed to alveolar ventilation insufficient amounts.
