Local anesthesia is used for tissue infiltration and nerve block anesthesia infiltration anesthesia is mostly used for minor surgical and dental procedures nerve blocks in addition are used for diagnostic procedures and pain management as well the uses of local infiltration anesthesia include subcutaneous fat tissue under the skin infiltration for iv placement superficial shave biopsy suturing. Conclusion local infiltration analgesia significantly reduces pain intensity on standing and mobilization and rescue analgesic consumption compared to femoral nerve block without causing significant side effects the superior analgesia in the lia group may result from the secondary injection at 23h postoperatively and needs to be further evaluated in future studies no differences were found in home discharge quality of life and hip dysfunction between the groups. Regional blocks have several potential disadvantages when compared with infiltration anesthesia the advantages of infiltration anesthesia are listed in box 1 in addition the complications of local anesthesia such as intravascular injection and nerve damage are principally associated with regional block techniques. So you can give a buccal infiltration in the maxillary region and the anaesthetic will penetrate the bone as it is quite thin and numb that region a nerve block is when you inject much further up the nerve branch and aneasthesise more of the nerve
