A

A wound made aseptically by a scalpel or cautery in a prepard site. Closure is performed easily, and first intention healing occurs due to the close correct approximation of the tissue

87
Q

Laceration

A

An accidental wound created in a contaminated matter (irragular tear of flesh). Closure could be difficult, infection very possible, could be secondary or third intention. Less than 6rs old is golden time to fix

88
Q

Puncture

A

A hole or wound made by sharp pointed object usually teeth. Often close easily, but usually never benaficial due to bacteria its better to leave it open to drain

89
Q

First intention healing

A

Healing usually follows the initial suturing of incised and correct closed wound. Usually fast with no complications, little scare tissue. “side to side” healing.

90
Q

Second intention healing

A

Wounds that failed to heal or should not be healed by first intention due to: infection, excessive trauma, loss of tissue, inadaquate approximation. Causes scare tissue and area will not grow back hair. Granulation tissue (proud flesh)

The surgeon waits 3-5 days after injury to close the wound, granulation tissue must be present and no signs of infection. Surgeon will then debride the wound and suture with primary closure

92
Q

Secondary closure

A

Can be done up to 1 month after initial wound. Heals by second intention, the granulation tissue is removed and the wound is resutred with primary closure. Rids wound of infection, creates healthy tissue and reduces scar tissue

93
Q

Dihiscence

A

Partiale seperation of a wound that has been healing before complete healing has occured

94
Q

Antiseptic

A

Chemicals used to inhibit or prevent the growth of microbes on living tissue

95
Q

Disinfectant

A

Chemicals used to inhibit or prevent the growth of microbes on inanimate objects

96
Q

Sanitize

A

Reduce the number of microbes to a safe level

97
Q

Sterilize

A

Eliminate all microbes (inactivates or kills)

98
Q

Biocide

A

Kills living organisms

99
Q

A

Instructed doctors to wash hands and death/infection rates decreased. His work was largly unappreciated

110
Q

A

Inspired by Pasteur’s work lead him to spraying instruments, incisions, and dressings with carbonic acid. Had sureons wear clean gloves and wash hands before and after surgery using 5% carbonic acid
